Hi Jon! Thanks for your reply! I've tested it by selecting the whole block. The error messages are gone. However, in the viewer, there are still the syntax lines only (under Log) and no output from R. Looking at the status bar, I cannot recognize any change during script execution. Looking at the taskmanager, startR.exe is started, but R is not, at least no visible. How does the plug-in work, is R started with a visible window if all works ok? Furthermore, I assume that the non-selecting cannot be the only reason for problems: If I use the "new" menu-item: R Boxplot, the whole script runs and is listed in the output viewer, but there is no box plot from R. Any idea? THANKS!
