[R] tcltk2 entry box

[Matthew]

Thank you very much, Greg, for the tkwait commands.

  I am just starting to try out examples on the sciviews web page to get 
a feel for tcltk in R and the tkwait.variable and tkwait.window seem 
like they could be very useful to me. I will add these in to my practice 
scripts and see what I can do with them.
