[R-gui] Simple way to ask user for text string with R-commander plugin ?

[Greg Snow]

Can you show some minimal code showing what you have tried?

One possibility is that you are not waiting for the pop-up box to close but returning the (empty) string value immediately, but there could be others.  Some code would help us to help you.
