I have had some comments on sqldf regarding its dependence on tcltk such as the second last sentence on this blog post:


sqldf does not directly use tcltk but it does use strapply in gsubfn for its parsing and strapply uses tcl from the tcltk package to it speed up -- there is also an all R version of strapply but the gsubfn package as a whole still depends on tcltk whether or not the user uses tcltk or not. I was thinking of changing the Depends:tcltk of gsubfn to Suggests:tcltk and then checking for tcltk availability at run time so if not available it would use the slower all R version; however, I was under the impression that all R platforms have a distribution of R that includes tcltk so in principle this should not be necessary.

Is that right regarding tcltk availability on various platforms? What is the situation here?
