Suggestions: a) Don't post in HTML format... your code appears corrupt. b) Don't do this. Read the Note in ?.First

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 ?
