Re: [R] Automating R script with Windows 7

Hi Jim, Please disregard my earlier post -- I have done some research and realized the space between after "program " was the the issue. I can now open RScript.exe from the command prompt using the abbreviated form: C:\PROGRA~1\R\R-2.11.1\bin\RScript.exe >From your earlier post, I understand the

Hey Jim, Thanks for the help. It took me a little bit of research but I got your solution to work. For everybody who has the same problem (1) remember to use the abbreviated names (no space) in folder paths: ex: 'C:\PROGRA~1\R\R-2.11.1\bin\RScript.exe' (2) put the folder with the R script to ru

Hi there, This will sound very stupid because I just started using R but I see you had similar problems. I just loaded a very large dataset (2950*6602) from csv into R. The format is ticker=row, date=column. Every time I want to compute basic operations, R returns "In Ops.factor: not meaningful
