Introduction to R Programming for Excel Users
 
01:45:58
R programming is rapidly becoming a valuable skill for data professionals of all stripes and a must-have skill for aspiring data scientists. Adding R programming to your data analyst skillset allows you to leverage powerful data visualizations, statistical analyses, and even machine learning in your daily work. In this presentation, Dave Langer illustrates how your knowledge of performing data analyses in Microsoft Excel gives you a unique foundation for quickly learning how to apply R in your daily work. No knowledge of R coding is required for this meetup as Dave will illustrate scenarios in Excel and then walk through how each Excel scenario is implemented in R. Attendees will learn how: • Fundamental concepts of Excel (e.g., working with tables, collections of cells, and functions) translate 100% to working with data in R. • Excel pivot tables translate to R code. • Creating charts in Excel is very similar to creating data visualizations in R. • R offers visualizations not available in Excel out of the box. An Excel spreadsheet and R code will be made available prior to the meetup via GitHub for attendees interested in following along during the talk.

Combining R with Java for Data Analysis
 
51:05
Java is a general-purpose language and is not particularly well suited for performing statistical analysis. Special languages and software environments have been created by and for statisticians to use. Statisticians think about programming and data analysis much different from Java programmers. These languages and tools make it easy to perform very sophisticated analyses on large data sets easily. Tools, such as R and SAS, contain a large toolbox of statistical tools that are well tested, documented and validated. For data analysis you want to use these tools. In this session we will provide an overview of how to leverage the power of R from Java. R is the leading open source statistical package/language/environment. The first part of the presentation will provide an overview of R focusing on the differences between R and Java at the language level. We’ll also look at some of the basic and more advanced tests to illustrate the power of R. The second half of the presentation will cover how to integrate R and Java using rJava. We’ll look at leverage R from the new Java EE Batching (JSR 352) to provide robust statistical analysis for enterprise applications. Authors: Ryan Cuprak undefined Elsa Cuprak Elsa was a statistician for the Cardiology/Heart Failure and Transplant Departments at Yale School of Medicine. She is an expert in statistics as well as SAS and Excel. Elsa has a masters degree in Actuary Science from the University of Iowa and bachelors in statistics from the University of California Berkley.

Intro to Data Visualization with R & ggplot2
 
01:11:15
The R programming language is experiencing rapid increases in popularity and wide adoption across industries. This popularity is due, in part, to R’s rich and powerful data visualization capabilities. While tools like Excel, Power BI, and Tableau are often the go-to solutions for data visualizations, none of these tools can compete with R in terms of the sheer breadth of, and control over, crafted data visualizations. As an example, R’s ggplot2 package provides the R programmer with dozens of print-quality visualizations – where any visualization can be heavily customized with a minimal amount of code. In this webinar Dave Langer will provide an introduction to data visualization with the ggplot2 package. The focus of the webinar will be using ggplot2 to analyze your data visually with a specific focus on discovering the underlying signals/patterns of your business. Attendees will learn how to: • Craft ggplot visualizations, including customization of rendered output. • Choose optimal visualizations for the type of data and the nature of the analysis at hand. • Leverage ggplot2’s powerful segmentation capabilities to achieve “visual drill-in of data”. • Export ggplot2 visualizations from RStudio for use in documents and presentations.

R tutorial: Introduction to cleaning data with R
 
05:18
Learn more about cleaning data with R: https://www.datacamp.com/courses/cleaning-data-in-r Hi, I'm Nick. I'm a data scientist at DataCamp and I'll be your instructor for this course on Cleaning Data in R. Let's kick things off by looking at an example of dirty data. You're looking at the top and bottom, or head and tail, of a dataset containing various weather metrics recorded in the city of Boston over a 12 month period of time. At first glance these data may not appear very dirty. The information is already organized into rows and columns, which is not always the case. The rows are numbered and the columns have names. In other words, it's already in table format, similar to what you might find in a spreadsheet document. We wouldn't be this lucky if, for example, we were scraping a webpage, but we have to start somewhere. Despite the dataset's deceivingly neat appearance, a closer look reveals many issues that should be dealt with prior to, say, attempting to build a statistical model to predict weather patterns in the future. For starters, the first column X (all the way on the left) appears be meaningless; it's not clear what the columns X1, X2, and so forth represent (and if they represent days of the month, then we have time represented in both rows and columns); the different types of measurements contained in the measure column should probably each have their own column; there are a bunch of NAs at the bottom of the data; and the list goes on. Don't worry if these things are not immediately obvious to you -- they will be by the end of the course. In fact, in the last chapter of this course, you will clean this exact same dataset from start to finish using all of the amazing new things you've learned. Dirty data are everywhere. In fact, most real-world datasets start off dirty in one way or another, but by the time they make their way into textbooks and courses, most have already been cleaned and prepared for analysis. This is convenient when all you want to talk about is how to analyze or model the data, but it can leave you at a loss when you're faced with cleaning your own data. With the rise of so-called "big data", data cleaning is more important than ever before. Every industry - finance, health care, retail, hospitality, and even education - is now doggy-paddling in a large sea of data. And as the data get bigger, the number of things that can go wrong do too. Each imperfection becomes harder to find when you can't simply look at the entire dataset in a spreadsheet on your computer. In fact, data cleaning is an essential part of the data science process. In simple terms, you might break this process down into four steps: collecting or acquiring your data, cleaning your data, analyzing or modeling your data, and reporting your results to the appropriate audience. If you try to skip the second step, you'll often run into problems getting the raw data to work with traditional tools for analysis in, say, R or Python. This could be true for a variety of reasons. For example, many common algorithms require variables to be arranged into columns and for missing values to be either removed or replaced with non-missing values, neither of which was the case with the weather data you just saw. Not only is data cleaning an essential part of the data science process - it's also often the most time-consuming part. As the New York Times reported in a 2014 article called "For Big-Data Scientists, ‘Janitor Work’ Is Key Hurdle to Insights", "Data scientists ... spend from 50 percent to 80 percent of their time mired in this more mundane labor of collecting and preparing unruly digital data, before it can be explored for useful nuggets." Unfortunately, data cleaning is not as sexy as training a neural network to identify images of cats on the internet, so it's generally not talked about in the media nor is it taught in most intro data science and statistics courses. No worries, we're here to help. In this course, we'll break data cleaning down into a three step process: exploring your raw data, tidying your data, and preparing your data for analysis. Each of the first three chapters of this course will cover one of these steps in depth, then the fourth chapter will require you to use everything you've learned to take the weather data from raw to ready for analysis. Let's jump right in!

R Tutorial - Using the Data Frame in R
 
05:24
Discover the power of the data frame in R! Join DataCamp today, and start our interactive intro to R programming tutorial for free: https://www.datacamp.com/courses/free-introduction-to-r By now, you already learned quite some things in R. Data structures such as vectors, matrices and lists have no secrets for you anymore. However, R is a statistical programming language, and in statistics you'll often be working with data sets. Such data sets are typically comprised of observations, or instances. All these observations have some variables associated with them. You can have for example, a data set of 5 people. Each person is an instance, and the properties about these people, such as for example their name, their age and whether they have children are the variables. How could you store such information in R? In a matrix? Not really, because the name would be a character and the age would be a numeric, these don't fit in a matrix. In a list maybe? This could work, because you can put practically anything in a list. You could create a list of lists, where each sublist is a person, with a name, an age and so on. However, the structure of such a list is not really useful to work with. What if you want to know all the ages for example? You'd have to write a lot of R code just to get what you want. But what data structure could we use then? Meet the data frame. It's the fundamental data structure to store typical data sets. It's pretty similar to a matrix, because it also has rows and columns. Also for data frames, the rows correspond to the observations, the persons in our example, while the columns correspond to the variables, or the properties of each of these persons. The big difference with matrices is that a data frame can contain elements of different types. One column can contain characters, another one numerics and yet another one logicals. That's exactly what we need to store our persons' information in the dataset, right? We could have a column for the name, which is character, one for the age, which is numeric, and one logical column to denote whether the person has children. There still is a restriction on the data types, though. Elements in the same column should be of the same type. That's not really a problem, because in one column, the age column for example, you'll always want a numeric, because an age is always a number, regardless of the observation. So, for the practical part now: creating a data.frame. In most cases, you don't create a data frame yourself. Instead, you typically import data from another source. This could be a csv file, a relational database, but also come from other software packages like Excel or SPSS. Of course, R provides ways to manually create data frames as well. You use the data dot frame function for this. To create our people data frame that has 5 observations and 3 variables, we'll have to pass the data frame function 3 vectors that are all of length five. The vectors you pass correspond to the columns. Let's create these three vectors first: `name`, `age` and `child`. Now, calling the data frame function is simple: The printout of the data frame already shows very clearly that we're dealing with a data set. Notice how the data frame function inferred the names of the columns from the variable names you passed it. To specify the names explicitly, you can use the same techniques as for vectors and lists. You can use the names function, ... , or use equals sings inside the data frame function to name the data frame columns right away. Like in matrices, it's also possible to name the rows of the data frame, but that's generally not a good idea so I won't detail on that here. Before you head over to some exercises, let me shortly discuss the structure of a data frame some more. If you look at this structure, ..., there are two things you can see here: First, the printout looks suspiciously similar to that of a list. That's because, under the hood, the data frame actually is a list. In this case, it's a list with three elements, corresponding to each of the columns in the data frame. Each list element is a vector of length 5, corresponding to the number of observations. A requirement that is not present for lists is that the length of the vectors you put in the list has to be equal. If you try to create a data frame with 3 vectors that are not all of the same length, you'll get an error. Second, the name column, which you expect to be a character vector, is actually a factor. That's because R by default stores the strings as factors. To suppress this behaviour, you can set the stringsAsFactors argument of the data.frame function to FALSE Now, the name column actually contains characters. With this new knowledge, you're ready for some first exercises on this extremely useful and powerful data structure.

R Tutorial - Making Basic Graphics in R
 
05:39
Learn how you can create basic graphics in R. Join DataCamp today, and start our interactive intro to R programming tutorial for free: https://www.datacamp.com/courses/free-introduction-to-r One of the main reasons that both academic and professional workers turn to R, is because of its very strong graphical capabilities. Walking away from graphical point and click programs such as Excel and Sigmaplot can be quite scary, but you'll soon see that R has much to offer. The big difference is that you create plots with lines of R code. You can thus perfectly replicate and modify plots inside R. This idea nicely fits into the spirit of reproducibility. The graphics package, that is loaded by default in R, already provides quite some functionality to create beautiful, publication-quality plots. Of course, throughout time, also a bunch of R packages have been developed to create visualizations differently or to build visualizations in very specific fields of study. Examples of very popular packages are ggplot2, ggvis and lattice, but I won't talk about those here. Among many others, the graphics package contains two functions that I'll talk about: `plot()` and `hist()`. I'll start with the `plot()` function first. This function is very generic, meaning that it can plot many different things. Depending on the type of data you give it, `plot()` will generate different plots. Typically, you'll want to plot one or two columns from a data frame, but you can also plot linear models, kernel density estimates and many more. Suppose we have a data frame `countries`, containing information on all of the countries in the world. There's of course the name of the country, but also the area, the continent it belongs to and other information such as population and religion. If you have a look at the structure of this data frame, you can see that there are numerical variables, characters, but also categorical variables, such as continent and religion. How would `plot()` handle these different data types? Let's find out! Let's try to plot the continent column of `countries`. We do the selection using the dollar sign: Cool. It looks like R figured out that continent is a factor, and that you'll probably want a bar chart, containing the number of countries there are in each continent. It also automatically assigned labels to the different bars. Now, what if you decide to plot a continuous variable, such as the population: This time, the populations of the countries are shown on an indexed plot. The first country corresponds to the index 1, while the population of the fiftieth observation in the data frame corresponds to index 50. Of course it's also possible to plot two continuous variables, such as area versus population: The result is a scatter plot, showing a dot for each country. There are some huge countries with many people living there, but also many smaller countries with also less people. It makes perfect sense that area and population are somewhat related, right? To make this relationship more clear, we can apply the logarithm function on both of the area and population vectors. You can use the `log()` function twice: For every continent now, a stacked bar chart of the different religions is depicted. On the right, you conveniently see the axis showing the proportions of each religion in each continent. If you switch the two variables inside the plot function, for every religion, a stacked bar chart of the different continents is depicted. This means that the first element in the `plot()` function is the variable on the horizontal axis, the x axis, while the second element is the element on the vertical axis, the y axis. All these examples show that the plot function is very capable at visualizing different kinds of information and manages to display the information in an interpretable way. To better understand your numerical data, it's often a good idea to have a look at its distribution. You can do this with the `hist()` function, which is short for histogram. Basically, a histogram is a visual representation of the distribution of your dataset by placing all the values in bins and plotting how many values there are in each bin. Say we want to get a first impression on the population in all of Africa's countries. With a logical vector, africa_obs, you can perform a selection on the countries data frame, to create sub data frame that contains only african countries.
