Hello,
I find a way to convert data in factor type to numeric :
data_numeric <- as.numeric(as.character(data_factor)).
It's treaky but works.

you could try as.numeric but without more details it is difficult to see
if this will work. How did you end up with a factor (e.g. through
import)?
No, don't use as.numeric(). Do follow Dimitris' advice.
But the question of how you got the factor data is good; you
can usually avoid getting factors to begin with.
