Computing

To change your tmp dir in R, using R:

dir.create('~/tmp')       ### or whatever you want to call it
dir.create('~/tmp/R')     ### or whatever if you want subdirectories
usethis::edit_r_environ() ### to open your .Renviron so you can edit it

and then add something like this to the .Renviron and save it:

TMPDIR='/home/<your user name>/<your temp folder name>/<temp sub folder>/'
TMP='/home/<your user name>/<your temp folder name>/<temp sub folder>/'
TEMP='/home/<your user name>/<your temp folder name>/<temp sub folder>/'

Note that tildas in the .Renviron file (such as ~/tmpdir/) do not work.
