Well, there is tcltk2 on CRAN that provides this. Currently, it is for 
Windows only, but the limitation is really because the package provides 
tile as a Windows binary (so that it works and uses the adequate tile 
version for this R package under Windows). I should rework this and 
simply tell in the package help that tile must be installed manually on 
other platforms.

Note that L am currently reworking tcltk2, so that change will be 
available... in the couple next months.

Best wishes for 2007,
