I think improvements in the RNG is a situation where backward
compatibility is not really going to be lost, because people can specify
the old generator, they just will not get it by default. My opinion is
that the default needs to generally be the best option

Kinderman-Ramage (PR#2846)
Hi,
Our department has detected a bug in the implementation of the
Kinderman-Ramage generator for normal random variates in version
1.7.0, which can be seen from the below R session.
(Consecutive calls for chisq.test(...) always gives p-values very
close to 0.)
We have already encountered this bug in version 1.6.2
The error is in file
R-1.7.0/src/nmath/snorm.c
Here is a patch for this file to

Buggy Kinderman-Ramage (PR#2846)
Unfortunately, RNGkind is buggy. It will not generate warnings
except the full name "Buggy Kinderman-Ramage" is supplied for normal.kind.
match.arg is supposed to be called before "==" comparison.

Yes, pretty much.

set.seed
I'm running into problems with set.seed--maybe I'm misunderstanding
something.
I'm running R 1.5.1 on Windows 2000.
I'm basically trying to capture the random seed so that I can reproduce a
simulation if it's necessary later. Using set.seed, I can certainly get
reproducible results, but not the results I get on the first pass. Here's
an example:

I would appreciate it if anybody has any comments on the following.
Please do not comment on the R functions themselves, since they merely
mimic a (bivariate simplification of a) C routine called from S.

A bug in the R Mersenne Twister (RNG) code?
I wonder how useful a (set of?) "time machine" functions which look up
/infer things like this based on a date would be. Could ease the pain of
changes generally, though not remove it completely.

Density function for non-central t distribution
Hi,
I've written some C code for density evaluation of the non-central t distribution. It works
with the R-1.7.1 source code if placed in the src/nmath directory and after appropriate
changes are made to Makefiles, to the dt function in src/library/base/R/distn.R etc.
I haven't read a lot of R source code so it may need some R-ification, but I've tried to use the

Problems with pf() with certain noncentral values/degrees of freedom combinations
Hello all.
It seems that the pf() function when used with noncentral parameters can
behave badly at times. I've included some examples below, but what is
happening is that with some combinations of df and ncp parameters,
regardless of how large the quantile gets, the same probability value is
returned. Upon first glance noncentral values greater than 200 may seem
large, but they are in
