About an introduction to R for SAS, SPSS, and STATA users

R is a free and powerful software for data analysis and graphics that is rapidly disrupting the market for data analytical tools and software. It is flexible (no need to wait 6 months for updates), extremely comprehensive (over 6000 packages), cross-platform, and has a great community. However, if you come from another statistical software tool it can be a challenge to master the versatility of R. Enter DataCamp’s new interactive course Introduction to R for SAS, SPSS, and STATA Users. An ideal course for those switching from SAS, SPSS or STATA to R. This course:

  • Introduces R jargon using language you’re familiar with.
  • Points out the errors you’re most likely to make. For example, many R functions let you specify which data set to use in a way that looks identical to SAS, but which differs in a way that is likely to lead to perplexing error messages.
  • Demonstrates add-on packages that produce output that is similar your current software’s. R’s built-in functions tend to provide surprisingly sparse output.
  • Covers material to help you migrate to R, or to integrate the use of R into your current software.

In total the course contains over 16 hours of material, 20 chapters, and over a 120 interactive exercises.

ggvis tutorial: become a data visualization expert with RStudio

The latest interactive course in the RStudio track is now available on DataCamp: ggvis tutorial. The first part of the tutorial is available for  free, so everyone can now learn interactively how to start creating stunning ggvis data visualizations in R. All courses in the RStudio track are self-paced, and combine challenging interactive exercises with to the point videos. Garrett Grolemund, master instructor at RStudio and R enthusiast, is your guide along this journey.

Check out the full course, or take the free preview.

ggvis tutorial

What is ggvis?

ggvis is the new standard tool for data visualization in R by RStudio. It lets you create static and interactive graphs to display distributions, relationships, model fits, and more. Similar to ggplot2, ggvis uses the grammar of graphics. The grammar provides an intuitive framework that lets you describe – and make – any plot that you can think of in your head. By learning the four components of the grammar, you empower yourself to make thousands of different types of ggvis data visualizations.

Best of all, ggvis plots are true web documents. You can save them as png’s for publication, but they come ready to be shared over the internet. Each ggvis plot can be viewed in a web browser, which opens opportunities not available in R’s native graphics device. For example, with a one or two lines of code, you can turn a ggvis plot into an animation or an interactive data exploration tool. This enables you to do rich data visualizations for analytics, communication and the web.

What is the ggvis tutorial?

This interactive ggvis tutorial will teach you how to use the ggvis package to make data visualizations like a pro. You’ll learn how to use the grammar of graphics to turn your data into sophisticated, layered graphics; and how to customize those graphics. Along the way, you will learn how to visualize statistical transformations of your data, as well as how to add interactive components to your graphs, such as sliders, checkboxes and more. Multiple ggvis examples are provided. Topics covered are:

  • Chapter One: The Grammar of Graphics
    Learn the philosophy that guides ggvis and discover a clear, logical way to think about data visualization.
  • Chapter Two: Lines and Syntax
    Examine each part of the grammar and learn the special syntax that ggvis introduces to make it easier to think about plots.
  • Chapter Three: Transformations
    Learn to build statistical transformations with ggvis’ compute functions, visualize the results, and how to integrate the dplyr package.
  • Chapter Four: Interactivity and Layers
    Create graphs that can be controlled through sliders, text fields, and other widgets. Build sophisticated, multi-layered graphs.
  • Chapter Five: Customizing Axes, Legends and Scales
    Change the appearance of axes and legends in your plots, and use ggvis’ scale system.

The DataCamp ggvis tutorial provides 10 videos, 30 exercises, and a surprise interview with one of the co-creators of ggvis. Go to the full course, and take the free preview.

Become a data scientist in 8 steps: the infographic

This post was written by the team behind DataCamp, the online interactive learning platform for data science.  

After being dubbed “sexiest job of the 21st Century” by Harvard Business Review, data scientists have stirred the interest of the general public. Many people are intrigued by this job, namely because the name has an interesting ring to it. But it is exactly the name that also raises a lot of questions. Because what is a data scientist and what do data scientists do exactly? Many of us who devote their lives to data science have frequently been confronted with questions like these.

The answers to these questions are mostly not as straightforward as you would expect: a short search on Google with the string of words “How to become a data scientist” shows that the concept has different meanings to different people. In addition, many articles indeed suggest various tools, courses and applications for people to become a data scientist, and with good reason: the options are unlimited. But let’s face it, for someone that is not familiar with the field, this advice may sometimes seem like a jungle of information. What’s more, they could work demotivating: the descriptions are sometimes fearfully long and the many details often hit the readers as an overwhelming avalanche.

DataCamp’s Guide to Become a Data Scientist

With all this in mind, DataCamp decided to help those who can’t see the forest for the trees: we designed a step-by-step infographic that clearly outlines how you can become a data scientist in 8 easy steps.  This visual guide is meant for everyone that is interested in learning data science or for everyone that has already become a data scientist but wants some additional resources for further perfection.  The infographic is called “Become a data scientist in 8 easy steps”. Have a look at it!

Complete dplyr tutorial for data analytics and data manipulation in R

DataCamp just launched its latest interactive course: dplyr. This new course was developed in close collaboration with Garrett Grolemund, RStudio’s master instructor. By taking this dplyr tutorial, you will be challenged one step at a time to master the essentials about transforming data sets fast and intuitively with the dplyr package. Start the course here.

The dplyr package is an exciting new chapter in the mission to bring painless data manipulation to the crowd. It is an R package that provides you with a fast and intuitive way to transform data sets with R. dplyr is the successor of plyr and is mainly authored by Hadley Wickham and Romain Francois. It is designed to be intuitive and easy to learn, thereby making “doing things” in R more user friendly.

This dplyr tutorial introduces five key functions to straightforwardly manipulate data: select, mutate, filter, arrange and summarize. Thanks to optimization in C++, these functions allow you to work extremely fast with larger data sets. These ‘dplyr verbs’ can be understood as the atoms that combine to powerful molecular operations which can handle around 90% of data manipulation tasks. As such, dplyr lets you, as a data scientist, accomplish more things, with more data, in less time. However, dplyr isn’t limited to these five functions; it also enables automated groupwise operations in R, it provides a standard syntax for accessing and manipulating database data with R, and much more. All of this and more is covered and explained in this DataCamp course (check out the contents of the course).

To help you fully grasp the power and ease-of-use of dplyr, DataCamp has developed a brand new interactive course together with Garrett Grolemund. Garrett is a Data Scientist and Master Instructor at RStudio, holds a Ph.D. in Statistics, and specializes in teaching. He is the author of Hands on Programming with R, as well as Data Science with R, an upcoming book from O’Reilly Media. He taught people how to use R at over 50 government agencies, small businesses, and multi-billion dollar global companies.

The dplyr tutorial

In the dplyr tutorial, you will learn how to use dplyr to perform basic data manipulation tasks using the five dplyr verbs, as well as combining these to solve challenging problems. You’ll also learn about groupwise operations using group_by(), about the pipe operator to chain your operations, and about the tbl structure which provides a cleaner layout so you can better understand your data. Finally, you will learn how to use the dplyr syntax to access data stored in a database outside R.

The course is set up in DataCamp’s interactive learning platform that aims to enhance your learning experience by allowing you to learn by doing. The course is comprised of 10 sections distributed over five chapters and each section has an instructional video by Garrett, followed by a vast set of interactive exercises. As such, the concepts that are introduced during the video lecture are directly tested through challenging assignments with tailored feedback to consolidate your knowledge step by step. You will effectively learn hands on instead of losing time with suboptimal solutions like a four-hour screencast or webinar.

Complete data.table tutorial: Data analysis the data.table way

Together with the key people behind the data.table package, Matt Dowle and Arun Srinivasan,  DataCamp developed a brand new interactive course to bring your data analysis skillset up to date with the essentials of the powerful data.table package. Learn more on the data.table tutorial… 

The popularity of the data.table package is increasing and with good reason. Not only is the number of package downloads rising rapidly, but data.table is also talk of the R town given the numerous presentations of Matt and Arun at conferences such as useR!2014, EARL, R/Insurance and R/Finance.

Data.table allows you to reduce your programming time as well as your computing time considerably, and it is especially useful if you often find yourself working with large datasets.  For example, to read in a 20GB .csv file with 200 million rows and 16 columns, data.table only needs 8 minutes thanks to the fread()function.  This  is instead of the hours it would take you with the read.csv() function. Once you understand its concepts and principles, the speed and simplicity of the package are astonishing!

On the data.table tutorial

However, to get the most out of data.table’s functionalities, you first have to overcome its learning curve: even though the syntax is not extremely difficult, it does take some practice to fully grasp it so its built-in functionalities can make your life easier. This is exactly why DataCamp has made an interactive online course on the data.table package for R and it has done so in collaboration with the key people behind it, namely Matt Dowle, main author, and Arun Srinivasan, co-author and major contributor. The data.table tutorial, which is unique as it is the only one of its kind, is called Data Analysis: the data.table way. It is designed to help you get started with the essentials of the data.table package. Among other things, you will learn all there is to know about operations such as selection and grouping in DT[i, j, by], and intermediate topics like chaining, setting keys and the different join types.

data.table tutorial

The course is set up in DataCamp’s interactive learning platform that aims to enhance the learning experience by centering on learning-by-doing.
