library(MASS)
set.seed(123)
n <- 1000
k <- 50
r <- matrix(rweibull(n*k, shape = 0.8, scale =2), k)
m <- t(apply(r, 2, function(x) coef(fitdistr(x, "weibull"))))

Please use a meaningful subject on your posts to r-help and trim them
so that they don't include the literally thousands of lines of garbage
that were at the end of your post.
