Hi Sir/Madam, I am calling R from an ASP.NET project. The outputs are a chart and cor(P1,P2). The exe file is in c:\program files\R\R-2.11.1\bin\rscript.exe, when I the asp.net project opens cmd.exe, and run r - -vanilla< r_sample.r , it says r is not recognized as defined command. (r_sample.r location is in bin of R). I also register Rscript.exe as exe file in windows, but it still shows an error. Really appreciate your hint. Regards Mahdieh [[alternative HTML version deleted]]
