<p>As a beginning R user, it’s OK to let your working direction be your home directory, documents directory, or any other weird directory on your computer. But you’re nine chapters into this book, and you’re no longer a rank beginner. Very soon now you should evolve to organizing your projects into directories and, when working on a project, set R’s working directory to the associated directory.</p>
<p>You can set the working directory from within R but <strong>we</strong> <strong>do not recommend it</strong>:</p>
<div class="cell">
<pre data-type="programlisting" data-code-language="downlit">setwd("/path/to/my/CoolProject")</pre>
<pre data-type="programlisting" data-code-language="r">setwd("/path/to/my/CoolProject")</pre>

<p>There’s a better way; a way that also puts you on the path to managing your R work like an expert. That way is the <strong>RStudio</strong> <strong>project</strong>.</p>

<p>Call your project <code>r4ds</code> and think carefully about which subdirectory you put the project in. If you don’t store it somewhere sensible, it will be hard to find it in the future!</p>
<p>Once this process is complete, you’ll get a new RStudio project just for this book. Check that the “home” of your project is the current working directory:</p>
<div class="cell">
<pre data-type="programlisting" data-code-language="downlit">getwd()
<pre data-type="programlisting" data-code-language="r">getwd()

<p>Now enter the following commands in the script editor, and save the file, calling it “diamonds.R”. Next, run the complete script which will save a PDF and CSV file into your project directory. Don’t worry about the details, you’ll learn them later in the book.</p>
