Hello, I am trying to build some dialog boxes but I am having problems. I'm using R-2.13.1 in Windows 7
I want to have 4 numerical entry boxes and 3 radiobuttons in a row ( 4 rows) for entry data
and 2 rows for output with a button for 'compute' and another for ;quit'
Can somebody indicate a tutorial or an example with similar type of dialogs?
Thanks
