I am getting warnings and empty popup boxes when compiling and loading R packages that depend on tk. They say that tk was not installed correctly.
I am using homebrew, but I can't tell which package might provide a correct install of tk, or if it would conflict with the existing (but broken) installation.
What is the recommended way to install enough of tk on OSX so that an R package with tk as a dependency (e.g. RNCEP) R will compile without giving this warning?
Here is the warning that I get when trying to load an R package that depends on tk.tcl:
Warning message: In fun(libname, pkgname) : Can't find a usable tk.tcl in the following directories: /System/Library/Frameworks/Tcl.framework/Versions/8.5/Resources/Scripts/tk8.5
