It's a build issue relating to Tcl/Tk, not specifically Rcmdr (Rcmdr does something slightly weird[*] with the fonts too, but this seems to be orthogonal to the ugly-font issue).
To see the issue quickly, try library(tcltk) .Tcl("::tk::pkgconfig get fontsystem") With CRAN 3.3.3, I get <Tcl> xft and likewise with a local nightly build of R-devel, but CRAN 3.4.0 says > .Tcl("::tk::pkgconfig get fontsystem") Error in .Tcl("::tk::pkgconfig get fontsystem") : could not find function ".Tcl" as does a local build of R-patched (???!!!). This is pretty weird. I'll see if I can dig up some more about where the difference is. -pd [*] Try library(tcltk); demo(tkfaq) then library(Rcmdr) and watch the font change in the tkfaq window. > On 15 May 2017, at 23:17 , Fox, John <j...@mcmaster.ca> wrote: > > Dear Jose, > > It's a bit difficult to respond to your latest messages because you sent so > many of them. > > I'm not entirely sure what's producing your font problems -- perhaps Simon > will have some additional ideas -- but you should be aware that you can't > load the Rcmdr package -- or, more generally, the tcltk package -- without > XQuartz (or another X11 system).
