[R-SIG-Mac] loading Rcmdr, R-Tcl/Tk errors due to X11

[Jan de Leeuw]

I run R from the terminal, from the Aqua GUI, from Carbon/Cocoa
emacs, or from X11 emacs. In order to make sure that X11 is
always available I start X11.app from the login items in system
preferences. This is not enough, because running R from carbon/cocoa  
emacs cannot
find $DISPLAY even if X11.app is running and it is defined in .tcshrc
-- so in addition my Rprofile.site has

local({
        options(device="x11")
        options(repos="http://cran.r-project.org")
        options(pkgType="source")
        Sys.putenv(DISPLAY=":0.0")
     })

.First <- function() {
	cat("\n   Welcome to Jan's R-2.3.0 !\n\n")
	}

This guarantees that library(tkrplot) or library(tcltk) always
works in all my different GUI's.
