[R-SIG-Mac] Rcmdr & tcltk

[Dan Putler]

Hi Cormac,

The safest thing to do is to launch X11 _before_ starting R (R won't  
start X11 itself). In addition, before loading the R Commander  
package, I would do a binary installation of all of R Commander's  
required packages (the list can be found on the R Commander web  
site). On the Mac you are using the same package tarball as you do on  
Linux. When you install the R Commander package, one of the things it  
does is to make sure that all of its support packages are available,  
and if some are missing, it attempts to do a source installation of  
missing packages. A number of the support packages have C and fortran  
code that needs to be compiled as part of the their installation. As  
a result, to install these packages from source you also need to have  
Apple's Xcode tools installed (which are on the software CDs that  
came with your Mac) and a fortran complier (which didn't come with  
your installation CDs, but can be obtained from several sources, and  
is an often discussed topic on this list). Although, my guess is that  
you will find the binary installation route an easier choice.
