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")
}
The connections variable will be local to .First, and will disappear
after that function is done. To save the variable into the global
environment, use
connections <<- read.csv("connections.csv", header=TRUE)
instead.

... 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!
