I think that you are correct. R has the annoying habit of
converting character data to factors when you don't want it to while
it is importing data. This is because the in the option
stringsAsFactors is set to TRUE for some weird historical reasons.

Yes, it is also possible. I usually use
as.numeric(as.character(some.factor.which can.be.transformed.to.numeric))

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

Hi David,
Thanks for the prompt answer.
In this file, I have cut the data to the first 15 columns.
Here is the code:
t2 - read.csv('Test2.csv', sep=,, header=TRUE)
Test2[2,2]
[1] 18.72
1994 Levels: 0.24 0.33 0.49 0.53 0.65 0.67 0.72 0.76 0.88 0.9 0.94 ... 98.88
Test2[2,2]+1
[1]

The stringAsFactors = False option did not work either.
False FALSE
in addition Vincent was getting an error since he used stringAsFactors, instead
of stringsAsFactors as the argument name.
