Dear all I do not usually post to R-devel, but I started to test R-2.5.0dev and encountered strange difference from 2.4.0 when loading Rgui under WXP. Both R builds are from CRAN executables and part of .Rprofile file is not executed in R-2.5.0. Here is my .Rprofile file contents --------------------------- options(chmhelp=TRUE) require(graphics) require(utils) RNGkind("Mersenne-Twister", "Inversion") par(bg="white") # this is not evaluated library(fun) # this is not evaluated data(stand) # this is not evaluated --------------------------------- Here you can see output from console. R version 2.4.0 Under development (unstable) (2006-08-02 r38773) Copyright (C) 2006 The R Foundation for Statistical Computing ISBN 3-900051-07-0 <snip> Loading required package: graphics Loading required package: grDevices [1] TRUE Loading required package: utils [1] TRUE Attaching package: 'fun' The following object(s) are masked from package:grDevices : hcl The following object(s) are masked from package:base : interaction so everything goes OK. but R version 2.5.0 Under development (unstable) (2006-12-16 r40209) Copyright (C) 2006 The R Foundation for Statistical Computing ISBN 3-900051-07-0 <snip> Loading required package: graphics [1] TRUE Loading required package: utils [1] TRUE Error: could not find function "windows" [Previously saved workspace restored] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ When I now issue par(bg="white") or library(fun) after R starts it is loaded OK. Is there anything I am doing wrong? I did not found anything in recent R-devel archives about different startup behaviour of R2.5.0. Best regards Petr PikalPetr Pikal petr.pikal at precheza.cz
