R Sig Mac Problem Loading Tcl Tk Interface On R For Mac

Posted on by

That FAQ is about using Aqua Tk and R.app, not R (see also item 8): I happiiy use Aqua Tcl 8.5.x with the command-line R, and with front ends designed just to launch a Tk interface. Prof Brian Ripley That theme is only available in Mac builds of Tk, not X11 ones. You can build R for yourself to use Mac Tcl/Tk (I tend to use the ActiveTcl distribution), and then the Mac theme is the default. But you will then need to use command-line R and not R.app (which is quite sensible if you are using Rcmdr as your console).

Caveat. I know almost nothing about homebrew other than its function and the fact that users of it often have problems with installing R properly. The CRAN page for the Mac R 3.4.2 fork says:

Problem

-------begin-------
Contains R 3.4.2 framework, R.app GUI 1.70 in 64-bit for Intel Macs, Tcl/Tk 8.6.6 X11 libraries and Texinfo 5.2. The latter two components are optional and can be ommitted when choosing 'custom install', they are only needed if you want to use the tcltk R package or build package documentation from sources.

So it makes me wonder if you need to add the correct versions of the underlying system packages in a manner that your homebrew installation can find them. (the 3.3 fork uses a differnt version of Tcl/Tk.)
