In my computer:
There are three files in /etc/R
Renviron
and Rprofile.site
,Renviron.site
,
I can not find Rprofile
anywhere. Is that a proper status?
What is the difference beetwen Rprofile
,Renviron
and Rprofile.site
,Renviron.site
?
Rprofile. site is the site-wide startup profile - it gets searched for, and run, BEFORE . Rprofile and it will overwrite the base package. . Rprofile is a user startup profile that gets searched for and sourced AFTER Rprofile. site and loads stuff into the workspace rather than overwriting the base package.
Rprofile is located in the users' home directory ( ~/. Rprofile on MacOS/Linux). This . Rprofile is run whenever you start up R.
Renviron file in your Home Directory. Find your Home directory by clicking on the Home button in the Files pane of RStudio. Then, simply create a new text file (File > New File > Text File) and save it as . Renviron .
One easy way to edit your . Rprofile file is to use the usethis::edit_r_profile() function from within an R session. You can specify whether you want to edit the user or project level . Rprofile.
The name of the file is .Rprofile
rather than Rprofile
. I got this code after doing a search in SO for '[r] .rprofile' and finding this answer:Locate the ".Rprofile" file generating default options
file.path(getwd(), ".Rprofile")
[1] "/Users/davidwinsemius/.Rprofile"
Most OSes will hide "dot-files"/"system files" unless you force them to become visible.
You will find the various files described in the ?Startup
help page. The .Renviron
file is supposed to describe settings and locations of system resources; from `?Startup
Lines in a site or user environment file should be either comment lines starting with #, or lines of the form name=value. The latter sets the environmental variable name to value, overriding an existing value.
So the key-value pairs will be used to push those pairs to the system environment variable table. Rprofile.site
is supposed to contain code that creates starting conditions for everyone on a network, perhaps shared options such as the setting for stringsAsFactors=FALSE
,
... and .Rprofile
contains code that an individual user sets up and controls, perhaps user defined functions or packages to be loaded at startup.
Josh cited an answer by @flodel that deserves study: Locate the ".Rprofile" file generating default options
