Hi all,
I was playing with R-devel 2005-03-08 on winXP Pro (installed from Duncan's installer). My .Rprofile contains:
options(defaultPackages=c(getOption("defaultPackages"), "mypkg"), chmhelp=TRUE)
but "mypkg" has not yet been installed in the library/ directory of this installation. When Rgui starts, I do not get any error or warning, but upon running one command, I get:
Warning messages: 1: there is no package called 'mypkg' in: library(package, character.only = TRUE, logical = TRUE, warn.conflicts = warn.conflicts, 2: package mypkg in options("defaultPackages") was not found
This seems a bit strange... I would expect the warning to show up before the first prompt. Is this intentional?
It is normal. By default (options(warn=0)), warnings are collected and
(to quote the help page) `printed after the top-level function has completed'. Warnings during startup wait until a top-level command has been completed. It is done in the main REPL loop at main.c:362 (and also under some error conditions).
As to whether this is intentional: I don't know but it would be helpful to change it, so I will.
