[R] Get Information

[Greg Snow]

Your code creates the menu that will run the cascade function.  The cascade function gets a name from the user to save, but you don't do anything with the name other than return it, and the code that calls cascade does nothing with the return value.  If you want the text in the text window saved, then you will need to add that functionality to the cascade function, first you will need to extract the text from the text widget, then using R commands and the filename you can save the information (see the cat command for one way of doing this).
