Try rereading FAX 7.10, it explains why as.numeric() won't do it:
"In any case, do not call as.numeric() or their likes directly for the
task at hand as as.numeric() or unclass() give the internal codes"
I.e., the INTERNAL CODE of the factor is what as.numeric() is working
on rather t
I tested
as.numeric(as.character(Ratio))
and it works perfectly!
I still don't get why as.numeric(Ratio) was not enough, but at least
now I know how to deal with it.
Thanks for the tip, and sorry for missing the R-FAQ issue 7.10.
Cheers,

Have a look at the R-FAQ issue 7.10. It's a standard
problem
For more information about your variable try
str(variable).

Dear R list,
I would like to perform an ANOVA in a set of measurements, but I have
problems formatting the data.
The data is a two dimensional array containing two columns:
- "Stim" : the type of stimulation (string)
- "Ratio" : a ratio of two numeric values
Now, because some values are missing
6 matches
