Starting tcltk without Tk
Philippe, I'm not quite sure why you are asking on a Mac list, but the error comes from Tcl/Tk. I'd suggest asking on R-devel, the Tcl/Tk used in the R binary is the same for R 2.6.x and 2.7.0 so it must be a change in tcltk. Cheers, Simon

Hello, Up to R 2.6.2, I used to start Tcl *without Tk* (I need only Tcl for some part of my work, like a socket server written in Tcl only, for instance) with this code under Mac OS X (particularly on this system, because I don't want to start X11 just to use Tcl code, which is required for Tk!):
Sys.unsetenv("DISPLAY")
library(tcltk)
I got then the message "no DISPLAY variable so Tk is not available", but could work with Tcl without problems. Now, with R 2.7.0, I got the following and Tcl failed to load: Loading Tcl/Tk interface ... Error in fun(...) : no display name and no $DISPLAY environment variable Error : .onLoad failed in 'loadNamespace' for 'tcltk' Error: package/namespace load failed for 'tcltk' I try to locate the message "no display name and no $DISPLAY environment variable" in the code but I cannot find it. Could someone help me please? I understand that starting Tcl without Tk from R is not an intended behaviour, but would it be possible to include an option to do so?
