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 for factors" I believe it is because R does not read the data as numbers but I am not sure. Can anybody help? Thanks! -- View this message in context: http://r.789695.n4.nabble.com/Operator-not-meaningful-for-factors-tp791563p2124697.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
