[kepler-users] Kepler-R basic question

[ben leinfelder]

Hi Allen!
A few questions for you: 
a) can you run any of the getting started demo RExpression workflows that are included with Kepler? (e.g. 05-LinearRegression.xml)
b) what version of Kepler are you using and on which operating system?
c) could you provide us your sample workflow?

If you can run R from the command line by simply typing "R", then chances are good it's already in your PATH.

I'm not sure how to do this. I can see in the Tools>Check System Settings that PATH = env.PATH, but am unsure whether this is what I'm supposed to set, and if so, how.
