[R] Problems changing to number from character

[Carlos Morales]

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
