[R] tcltk2 entry box

[John Fox]

Dear Matthew,

For file selection, see ?tcltk::tk_choose.files or ?tcltk::tkgetOpenFile . 

You could enter a number in a tk entry widget, but, depending upon the
nature of the number, a slider or other widget might be a better choice. 

For a variety of helpful tcltk examples see
<http://www.sciviews.org/_rgui/tcltk/>, originally by James Wettenhall but
now maintained by Philippe Grosjean (the author of the tcltk2 package). (You
probably don't need tcltk2 for the simple operations that you mention, but
see ?tk2spinbox for an alternative to a slider.)

Best,
 John
