Hi Allen -- I changed the file name input so that the value was not surrounded by quotes (").
I changed the file name to match the file you attached to your email (capitalization). I took out the call to pairs(df) in the ReadFile actor because this error was showing in the logs: --------- 11/11/11 10:58:21.850 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] ERROR (org.ecoinformatics.seek.R.RExpression:fire:935) R standard error: 11/11/11 10:58:21.851 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] Error in plot.window(...) : need finite 'xlim' values 11/11/11 10:58:21.851 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] Calls: pairs ... localPlot -> plot -> plot.default -> localWindow -> plot.window 11/11/11 10:58:21.851 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] In addition: Warning messages: 11/11/11 10:58:21.851 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] 1: In min(x) : no non-missing arguments to min; returning Inf 11/11/11 10:58:21.851 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] 2: In max(x) : no non-missing arguments to max; returning -Inf 11/11/11 10:58:21.851 AM [0x0-0xad1ad1].org.kepler.build.runner.Kepler: [null] Execution halted And it gave me a [crazy?] zig-zag plot.
