Setup

There may be a difference between R and R Studio regarding the location of installed packages.

We have noticed at previous workshops that RStudio couldn't find libraries that were not installed through the RStudio package manager. This appeared to have been version dependent, and may not affect current releases. You can check for this (in case you have problems running the library() command) by issuing the command ... 

.libPaths()

...in R as well as in R Studio. The path should be the same in both.

In case you need to "tell" RStudio the location, you can define the path in a startup file. Create or edit a file called .Renviron in your home directory. Inside there define: 

R_LIBS=<Library Path of R installed packages>

Alternatively, you could use the R Studio package manger to install libraries.



Task:

  1. Download the file below to your working directory;
  2. load the file in R Studio;
  3. proceed to the first CHECKPOINT in the script.
