rrprofile

Startup script in Rprofile throws 'function not found' errors

I want R to load a certain file on initialization, so naturally I added a source command to my Rprofile so:

  .First <- function()
   {
         cat("\n   Welcome to R MotherFnorder!!!\n\n")
         setwd("/home/username/Code/R/")
       source("/home/username/Code/R/file.R")
   }

But now when I start R it throws a 'function not found' error for default functions like runif or rnorm. When I load the same file manually into the workspace I get no errors.

Solution

  • You don't need (or, really, want) to create a .First . If you put those lines into your .Rprofile they'll execute just fine. -- With the proviso @Pascal pointed out, that any function called in your file.R must have its library loaded first. So, near the bottom of your .Rprofile, just put

    library(whatever_packages_needed)
cat("\n   Welcome to R MotherFnorder!!!\n\n")
setwd("/home/username/Code/R/")
source("/home/username/Code/R/file.R")

    EDIT: I cannot reproduce your problem. I added these lines to the end of my .Rprofile:

    #testing SO problem with libloading
library(stats)
runif(10)

    And the console returns ten nice numbers.
