Re: [R] tcltk2 entry box
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).

[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.
