I needed to generate some data from the Inverse Gaussian distribution
but it is not in R. A google search took me to
http://www.maths.uq.edu.au/~gks/s/invgauss.html
which contains the documentation for the d, p, r, q functions with a
download link of the functions. The functions work fine in R.
I am curious why the facilities are not included in R. Is it for
legal reasons or just the lack or demand?

License-wise Gordon seems to be putting a non-profit clause of the code, which is incompatible with the GPL and the Debian guidelines. Wouldn't know whether he could be convinced to do otherwise, but he seems a reasonably friendly guy (I met him a couple of times when he was guest professor in Odense in 1999). -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
