Exercise
Try running the statistical computing environment called “R” . Type the following on the command line:
An error message will be displayed:

(where you replace
This loads the module for R which adds the respective application folder containing the binary of the application to the search path of your shell ($PATH). You can check this by running
Now try running R from the command line again.
This time the “R” environment should start. Use quit() to close it and to return to your shell. Log out and log back in.
Trying running R again.
You will notice that R is missing from your $PATH again.
Check the module man page (man module) to find the command that will make R available every time you log in.
