R Startup Arguments

A number of arguments that relate to startup can be appended to the R startup command (R in a shell environment). The following are particularly important:

--no-environ and --no-init: Tell R to only look for startup files (described in the next section) in the current working directory.
--no-restore: Tells R not to load a file called .RData (the default name for R session files) that may be present in the current working directory.
--no-save: Tells R not to ask the user if they want to save objects saved in RAM when the session is ended with q().

Adding each of these will make R load slightly faster, meaning that slightly less user input is needed when you quit. R’s default setting of loading data from the last session automatically is potentially problematic in this context. See Appendix B of An Introduction to R for more startup arguments.

Tip

A concise way to load a vanilla version of R with all of the preceding options enabled is with an option of the same name:

R --vanilla
