[R] / Operator not meaningful for factors

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?
