Hello everybody,
There is something that I do not get with scale function.
Say that I have a vector v <- c(1,2,3,4,5,6),
scale(v,center=TRUE,scale=TRUE) gives a new vector with 0 as mean and 1
as standard deviation.
but,
scale(v, center=FALSE,scale=TRUE) gives a new vector with a standard
deviation different from 1.
I would also expect a standard deviation of 1 in that case.
am I wrong ?
thanks
Eric Pellegrini
