If you are after the lognormal distribution, I would recommend you use the
lognormal functions from R itself. Check them out with
?dlnorm

If what you want is a lognormal distribution of n values you can use
the following transformations:
lognorm1 <- M*exp((rnorm(n)*sigma)-sigma^2/2.)
which gives a lognormal distribution such that:
mean(lognorm1)=M ;
var(lognorm1)=M^2*(exp(sigma^2)-1);
Changing the sigma (standard deviation) you alw
Dear R users,
My question is that how it is possible to generate some random numbers using
rnorm( ) function but in log transformed values.
Thank you,
Tobias
