(tkrplot doesn't work in Aqua.) 3) (a) Use the version of the tcltk R package which is distributed with R 1.9.1. (b) Use Tcl/Tk 8.4.x. My Mac I.T. administrator is working on an R + Tcl/Tk installation package for Mac OS X, but I can't do it myself because I don't have installation privileges on a Mac. You should install R 1.9.1 from CRAN (http://cran.r-project.org or your local mirror). This should include the tcltk R package, but not Tcl/Tk itself. If you have the developer tools (C compilers etc.), you can install Tcl/Tk as described in the R for Mac OS X FAQ: http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html in the section: the TclTk 8.4 headers and libraries (optional) which should install both Tcl and Tk in /usr/local/ This requires the X11 SDK (Software Development Kit), i.e. header files etc. which should be on the Panther Developer CD. If you don't have the developer tools, you can try the X11 Tcl/Tk installer at http://www.economia.unimi.it/R/ As far as I know, it shouldn't matter which order you install things in: X11 Tcl/Tk then R or vice versa. Once you have these two things installed, you should be able to type library(tcltk) from R, and it should find Tcl/Tk in /usr/local/ Then you can type tclvalue("auto_path") to see your Tcl search path, and you can try loading the Tcl/Tk extensions required by limmaGUI with tclRequire("Tktable") and tclRequire("BWidget") They should be installed in /usr/local/lib/Tktable2.8/ (or whatever version you use) and /usr/local/lib/BWidget-1.7.0/ (or whatever version you use) Let us know if you have any specific errors to report after installing X11 Tcl/Tk and R and then loading the tcltk R package, and tclRequire()-ing the Tcl/Tk extensions.
