R will download the packages from CRAN and install them on to your computer. You will not be able to use the functions, objects, and help files in a package until you load it with library. Once you have installed a package, you can load it with the library function:. This tells you that tidyverse is loading the ggplot2, tibble, tidyr, readr, purrr, and dplyr packages. Packages in the tidyverse change fairly frequently. There are many other excellent packages that are not part of the tidyverse, because they solve problems in a different domain, or are designed with a different set of underlying principles. In other words, the complement to the tidyverse is not the messyverse, but many other universes of interrelated packages.
The previous section showed you a couple of examples of running R code. Code in the book looks like this:. There are two main differences. Functions are in a code font and followed by parentheses, like sum , or mean. Other R objects like data or function arguments are in a code font, without parentheses, like flights or x. This is also valid R code. This book is not an island; there is no single resource that will allow you to master R. As you start to apply the techniques described in this book to your own data you will soon find questions that we do not answer. This section describes a few tips on how to get help, and to help you keep learning. If you get stuck, start with Google. Google is particularly useful for error messages. If you get an error message and you have no idea what it means, try googling it! Chances are that someone else has been confused by it in the past, and there will be help somewhere on the web. Start by spending a little time searching for an existing answer, including [R] to restrict your search to questions and answers that use R.
There are three things you need to include to make your example reproducible: required packages, data, and code. The easiest way to include data in a question is to use dput to generate the R code to recreate it. Do your best to remove everything that is not related to the problem. The shorter your code is, the easier it is to understand, and the easier it is to fix. Finish by checking that you have actually made a reproducible example by starting a fresh R session and copying and pasting your script in. You should also spend some time preparing yourself to solve problems before they occur. Investing a little time in learning R each day will pay off handsomely in the long run. One way is to follow what Hadley, Garrett, and everyone else at RStudio are doing on the RStudio blog. This is where we post announcements about new packages, new IDE features, and in-person courses.
You might also want to follow Hadley hadleywickham or Garrett statgarrett on Twitter, or follow rstudiotips to keep up with new features in the IDE. com : it aggregates over blogs about R from around the world. Twitter is one of the key tools that Hadley uses to keep up with new developments in the community. Jenny Bryan and Lionel Henry for many helpful discussions around working with lists and list-columns. html by Jenny Bryan. Genevera Allen for discussions about models, modelling, the statistical learning perspective, and the difference between hypothesis generation and hypothesis confirmation. Yihui Xie for his work on the bookdown package, and for tirelessly responding to my feature requests. Bill Behrman for his thoughtful reading of the entire book, and for trying it out with his data science class at Stanford.
The rstats twitter community who reviewed all of the draft chapters and provided tons of useful feedback. Tal Galili for augmenting his dendextend package to support a section on clustering that did not make it into the final draft. This book was written in the open, and many people contributed pull requests to fix minor problems. Special thanks goes to everyone who contributed via GitHub:. Thanks go to all contributers in alphabetical order: a-rosenberg , A.

The last step of data science is communication , an absolutely critical part of any data analysis project. There are lots of datasets that do not naturally fit in this paradigm, including images, sounds, trees, and text.
