Ah, you didn't provide a complete description of
your problem. gdata is a factor. You need to
read about converting factors to numeric, or
perhaps reconsider your method of creating or
importing gdata.
as.numeric(somefactor) does not extract the
printed value, it extracts the *order of the factor*.
> somefactor <- as.factor(c(1,2,6,4))
> somefactor
[1] 1 2 6 4
Levels: 1 2 4 6
> as.numeric(somefactor)
[1] 1 2 4 3
> as.numeric(as.character(somefactor))
[1] 1 2 6 4

[1] a b d c
Levels: a b c d
> as.numeric(somefactor)
[1] 1 2 4 3
Please read the posting guide, and follow the
instructions therein for providing a clear and
complete question. Plus, I think this is a FAQ.
