Hi, I agree the demos should work. But the R problem is one we've discussed. The Kepler installer puts R in place when Kepler is installed, so users should not encounter the problem that Edward did. Developers that are using SVN need to install R themselves. The 'null' message that you got is a problem that I thought we had fixed. I entered a bug request that makes the R actor produce a more intelligible error message when it can't find the R executable. Maybe in init() it should be doing a test of whether R is available and reporting a sensible error if it is not. This could also be solved withthe dependency tracking system that we are designing for modules.
