Hi Klaus,
Why not just use R's random number generator? See section 6.3 of
Writing R Extensions. It should give you the same sequence of
pseudorandom numbers on all platforms.

Our suspicion is that the reason is that some libraries are different
implemented on linux and windows (XP) compilers.

I think that you do not like to use rand
I cannot say what the problem is in your code, but in general it is
possible to get the same random sequences from Linux and Windows with
R's Mersenne Twister generator. If you generate long sequences (say 10s
of thousands) and then start doing comparisons involving remainders,

Hey guys,
I'm a (Java) integration architect.
We are currently stuck with SAS but I'd be happy to switch that to R! (of
course ;-).
Now, a big argument for the latter, is that we can integrate it seamlessly
with all our existing (java) apps.
Therefore: has anyone heard of a java API (like SAS

Hello all,
it seems my efforts in reading the manuals and help files aren't enough
so here I am. The question is, how would I go about linking a
pre-compiled DLL in to my package? I have previously successfully built
packages with Fortran and C source code, but now I'd like to take this

The diag() function appears to reject the first argument when it is a matrix,
and nrow and ncol arguments are also provided.
foo - matrix(c(1:4),2,2)
foo
[,1] [,2]
[1,]13

I think you are looking for something like RServe. http://rosuda.org/Rserve/.
It sets up R as a server which you talk to via TCP/IP. It has client
APIs for Java and a number of other languages.

My understanding is that providing nrow and ncol, you want to create a
diagonal matrix with those dimensions.
diag(pi, 6, 6)
and that by
diag(foo, 2, 2)
you really meant
diag(foo)[2]
Apologies if I misunderstood.

Yes (beware the length 1 case, though).
However, don't delete the bug report. That error message is just wrong:
if (is.array(x) length(dim(x)) != 1L)
stop(first argument is array, but not matrix.)

I wish the t.test function in stats would return the standard error.
It would be nicer for students if R simply reported the standard error
used to calculate the t value. I trolled for this in r-help and got
no answers, which I interpreted to mean that this is boring but
possibly not wrong.
