I'm a bit alarmed by the logic here. Unbiased sampling seems basic for a
statistical language. As a consumer of R I'd

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...

results used for comparisons in the tests. Since package testing is
usually for code checking rather than statistical results, not using the
best available generator is not usually an issue.
Most of my own package testing already specifies the generator, lots
uses "buggy Kinderman-Ramage" because tests were set up a long time ago.
I will have to change package setRNG which warns when the default
generator changes. (This warning is intentional because I was bitten
badly by a small change in the S generator circa 1990.)

Balancing backward compatibility and correctness is a tough problem
here. If this goes into base R, what's the best way to do it? What was
the protocol for migrating away from the "buggy Kinderman-Ramage"
generator, back in the day? (Version 1.7 was sometime between 2001 and
2004).

More files randomly corrupted
...re it out, I don't know whats causing this or where to start really. To make it worse someone told me there isn't anything in the samba code to cause this.
Finally all the files that seem to be corrupted when being read, seem to be intact on the file system they are stored on.

Which function can change RNG state?
Today I struggled for hours to understand some unexpected package test
results. It turned out that this is because package "parallel", buried deep
in my dependencies, calls runif() during it's initialization and in this way
changes the random number sequence. This seems to be a part of a more
general question--which kind of functions can we trust if we want to
preserve random

forgetful I can remember exactly one such change where behaviour was changed,

days of R 1.* days . [ Goes digging...] Yes, see `help(RNGkind)` which
details that R 1.7.0 made a change when "Buggy Kinderman-Ramage" was added as
the old value, and "Kinderman-Ramage" was repaired. There once was a similar
fix in the very early days of the Mersenne-Twister which is why the GNU GSL
has two variants with suffixes _1998 and _1998.

Windows .SYS Drivers

Problems Installing .Net 1.1 SP1
I just downloaded TurboDelphi from edn.emarcadero.com (the full 2006
package) and am trying to install it under wine. Installation stops
with a message that it needs DotNet 1.11 installed so I downloaded the
.Net package from Microsoft. For some reason, this version will not
install - I had previously tried .Net 2.0 and .Net 1.1. The link below

I am trying to install wine-20050211 on my second system, which runs
SuSE 9.2. After much faffing around I finally managed to download and
install bison, which allowed ./config to complete. A warning at the end
advised me to install xlib-devel or xfree86-devel. Googling around I
found the RPM for XFree86-devel for SuSE 9.1 so I downloaded it and

BUG report : 'rnorm' (LINUX, R 1.6.2) (PR#2682)
...orm(rnorm(1000000)),100)
The result is the p-value of a goodness of fit test (chisquare test).
It should be a uniform random number in [0,1].
However, if this test is repeated, one almost every time gets an
number near one (0.99...)
This problems happens only by using normal.kind="Kindermann-Ramage"
(the default). This bug also appears in all random variate generation
that depend on 'rnorm', like 'rgamma'.
With regards,

Well "problems in reproducibility" is a bit vague. Results would always
be reproducible by specifying kind="Mersenne-Twister" or kind="Buggy
Kinderman-Ramage" for older results, so there is no problem reproducing
results. The only problem is that users expecting to reproduce results
twenty years later will need to know what random generator they used.
