[R] Can I read a file into my workspace from Rprofile.site?
I am running R version 2.8.1 on Windows XP OS.
When I launch R, I would like to automatically read a file containing my
database connections, user ids, and passwords into my workspace.
I tried including this in my Rprofile.site file:
...
local({
old <- getOption("defaultPackages")
options(defaultPackages = c(old, "Rcmdr","RODBC",
"utils"))
})
.First <- function() {
library(utils)
setwd("C:/Documents and Settings/Administrator/My Documents/R")
connections <- read.csv("connections.csv", header=TRUE)
cat("\n Welcome to R Elaine!\n\n")
}
...
When I launch R, it does not give me any error. The working directory
appears to be set by the Rprofile.site file, but the connections object is
not in my workspace:
Welcome to R Elaine!
Loading required package: tcltk
Loading Tcl/Tk interface ... done
Loading required package: car
Rcmdr Version 1.4-7
> ls()
character(0)
Any suggestions for how to resolve are appreciated!

To save the variable into the global environment, use connections <<- read.csv("connections.csv", header=TRUE) instead. Duncan Murdoch> ... > > When I launch R, it does not give me any error.
