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. -ben On Nov 11, 2011, at 7:29 AM, Hurlbert, Allen Hartley wrote: > 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.
