[kepler-users] Kepler-R basic question

[Hurlbert, Allen Hartley]

Apologies for the basic question, but I'm brand new to Kepler.

Trying to create a basic workflow that reads in some data from a local text file (using ReadTable), manipulates it a bit (using an RExpression actor), and generates a plot.

However, it seems to be having trouble locating R (error message: "Problem writing input. There has been a problem running the R script! It may be due to an error in your script, ..., or it may not be on your path and cannot be located by Kepler... Because: the pipe has been ended.").

I definitely have R installed on my machine. The referenced section of the User Manual, states "the R 'bin' directory must be added to the PATH variable on the host computer." 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.

Thanks in advance,
Allen
