Hello all, First of all, thanks for your examples to calculate the mode value. But now my problem is the next: I have a?factor and I'm trying to convert it to number with as.numeric(x) but when I see the number it's different, I mean if I have: b<-1,042 d<-as.numeric(b) then when I show d, it appears 432 and I want to work with 1,042 because then I want to calculate the median of three values Thanks so much Carlos
If it is a factor, you have to convert to character first and then numeric: d <- as.numeric(as.character(b)) On Mon, Sep 15, 2008 at 1:26 PM, Carlos Morales <carlosmoralesdiego at yahoo.es> wrote:> Hello all, > > First of all, thanks for your examples to calculate the mode value.

I think your problem is the comma. Why are you using it? b <- 1042> str(b)num 1042 Cheers, Alex On Mon, 2008-09-15 at 17:26 +0000, Carlos Morales wrote:> Hello all, > > First of all, thanks for your examples to calculate the mode value.

Try this:
d <- as.numeric(gsub(",", ".", as.character(b)))
