Hi!
I would like to be able to create formulas automatically. For example, I
want to be able to create a function that takes on two values: resp and

, there is a way fitdistr can also compute difficult data.

Sorry, didn't notice that you *did* mention dtnorm is part of msm.
Ignore that part of the advice...

Hi, Jose/John,
Here's an example to help Jose and highlights John's advice. Also
includes set.seed which should be included in all simulations posted to
R-help.
set.seed(42)

sigma - 5
n - 3
nsim - 1
m - matrix(rnorm(n * nsim, mu, sigma), nsim, n)

Hi, all,
I'm looking a utility for removing a directory from within R. Currently,
I'm using:
foo - function(...) {
mydir - tempdir()
dir.create(mydir, showWarnings = FALSE, recursive = TRUE)
on.exit(system(sprintf(rm -rf %s, mydir)))
## do some stuff in mydir
invisible()
}
Please ignore. I forgot ?unlink had a recursive argument.
Thanks.
