[R] replacing values in a vector

[Philippe Grosjean]

n <- rep(0, length(v)) #Or replace 0 by the initial value you want in the
vector n
n[is.na(v)] <- NA

Objet : [R] replacing values in a vector


Hi all,

there is a vector v with several NAs. I want to create a new vector n of
the same length as v and the same NAs as in v and tried this:

n <- vector(length=length(v), mode="numeric")
replace(n, which(is.na(v)), NA)

but this does't work, all values in n are 0. What went wrong?

Thanks, Sven
