Hi all -
Long-time user, first-time poster.
I added a .First function to my Rprofile.site file to check for updates, clean
the console, and put some fun quotes on startup. This used to work without
error. I hadn't used R (which I usually play with in RStudio) in a few weeks,
but when I started up recently and updated (R 3.1.0+ RStudio v 0.98.945),I got
a couple error messages. For context, here is my .First function:
.First <- function(){
suppressPackageStartupMessages(library(installr))
library(installr)
library(stats)
old.packages = installed.packages()[,1]
save(old.packages,
file="C:/Users/Owner/Documents/R/installedPackages.Rdata")
# load("C:/Users/Owner/Documents/R/installedPackages.Rdata")
# pull.packages = installed.packages()[,1]
# for (i in setdiff(old.packages, pull.packages))
# install.packages(i)
updateR()
cat("\014")
if (runif(1,0,1)>0.5) {
cat("Stately, plump Buck Mulligan...")
} else cat("as though\nyou were creating\na mathematical sandwich")
}
I was getting an error message about installr, but I added the suppress...
function as suggested in that error message, which worked like a gem. However,
I can't quite figure out how to address the other error message. Here it is:
Error installing package: Error in winDialog(type = "ok", message =
message_text) : winDialog() cannot be used non-interactively
Calls: .First -> updateR -> check.for.updates.R -> winDialog
Execution halted
I'm not sure what's going on here, but I'm guessing R runs .First functions in
non-interactive mode. I ham-handedly tried adding an > interactive=T line to
the .First function, but this didn't work.
Any suggestions would be much appreciated.
=) Brian
