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.

If you want you script to wait until you have a value entered then you
can use the tkwait.variable or tkwait.window commands to make the
script wait before continuing (or you can bind the code to a button so
that you enter the value, then click on the button to run the code).

Wow ! Very nice. Thank you very much, John. This is very helpful and just
what I need.
Yes, I can see that I should have paid attention to tcltk before going to
tcltk2.

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

Subject: [R] tcltk2 entry box
Is anyone familiar enough with the tcltk2 package to know if it is
possible to have an entry box where a user can enter information (such
as a path to a file or a number) and then be able to use the entered
information downstream in a R script ?
The idea is for someone unfamiliar with R to just start an R script that
would take care of all the commands for them so all they have to do is
get the script started. However, there is always a couple of pieces of
information that will change each time the script is used (for example,
a different file will be processed by the script). So, I would like a
way for the user to input that information as the script ran.
