[Rd] Including data in package for use by C functions

2008-09-15 Thread Ernest Turro

I think it is a little more complex than just installing and checking. tkProgressBar uses tcltk which works on the major platforms (unix/linux, mac, windows), but only if tk is installed and available. I believe that on mac tk is only available if X11 is used and if I remember correctly, if R
