Indeed, you can put all kinds of things in the Rprofile.

I use this:

#  =============================================   my own first-function
.First <- function(){
	cat("\n>>>  R 2.15.2   Rprofile van 13-02-2013   \n\nFunctions added:\t sinc()\t permute()\t combine()\n dice(n)\t countif()\t pplot()\t lplot()\n ln()\t xmatplot()\t ascii()\t chr()\n to.dec()\t to.hex()\tincr()\tdecr()\n as.sci()\tas.eng()\tnprint()\nVectors added: eps, ans, xpoints, xcols\nText:lorem\n\n")
cat("Default Packages:",getOption("defaultPackages"))
#  ==============================================

This gets printed after R's built-in message.

As this text states, I also put my own functions in the Rprofile. Works fine.

Best wishes,
