r - my rprofile is running multiple times

My .Rprofile always runs twice. I looked at this thread and think it might be because the slashes are going in various directions.

I only have code in the paths pointing at C:/Users/rileyj3/.Rprofile (results 1, 2 & 4). Does anyone know how to resolve?

expr path exists
file.path(getwd(), ".Rprofile") C:/Users/rileyj3/.Rprofile TRUE
file.path(Sys.getenv("HOME"), ".Rprofile") C:\Users\rileyj3/.Rprofile TRUE
file.path(Sys.getenv("R_HOME"), "etc", "Rprofile.site") C:/PROGRA~1/R/R-42~1.2/etc/Rprofile.site TRUE
Sys.getenv("R_PROFILE") C:\Users\rileyj3.Rprofile TRUE
Sys.getenv("R_PROFILE_USER") FALSE

library(tidyverse)
tibble(
  expr = c(
    'file.path(getwd(), ".Rprofile")',
    'file.path(Sys.getenv("HOME"), ".Rprofile")',
    'file.path(Sys.getenv("R_HOME"), "etc", "Rprofile.site")',
    'Sys.getenv("R_PROFILE")',
    'Sys.getenv("R_PROFILE_USER")'
  )
) |> 
  mutate(
    path = map_chr(expr, ~parse(text = .x) |> eval()),
    exists = file.exists(path)
  ) |> 
  knitr::kable()

CodePudding user response:

You can see the details of R read Rprofile files on the ?Startup help page.

R will look for both a site-wide and user-specific profile. Since you have a value set for R_PROFILE, that's considered a site-wide profile so it's run. Then when R looks for a user-specific value, it finds the one in your home directory so it runs that one as well. R doesn't check to see if the site-wide and specific files are the same. You should probably remove the R_PROFILE system environment variable since you seem to be setting a user-specific values there or move it to R_PROFILE_USER.
