If you run this you get sensible output, but whether it meets you
needs depends on what you meant by Exp(1):
> Y <- rnorm(100)
> Z <- rnorm(100)
> X <- exp(Y+Z)
If you are looking for methods to handle random variables in R, you
may want to look at the series of packages all beginning with "distr":
distr, distrDoc, distrEx, distrMod, distrSim, distrTeach, distrTEst.
