title: RStudio projects capabilities
body: <p>I'm starting to use RStudio and I found the option of creating Projects, which enables you "to divide your work into multiple contexts, each with their own working directory, workspace, history, and source documents" according to <a href="http://www.rstudio.com" rel="noreferrer">rstudio.com</a>.</p>
  
  <p>Are projects only used for package development? If not, can you show me any other typical situation where the features written above would allow you things (besides version control) impossible (or more difficult) to do in a normal workspace?</p>
