[R] rnorm using vector of means and SDs

[Phil Spector]

I think

t(mapply(rnorm,1000,vector_of_means,vector_of_sds))

will do what you want.

That is, I have a list/vector of say 100 means and another of the corresponding 100 SD's, and I want a matrix of 100 rows (one for each mean and SD pair) each having 1000 random samples.
