user supplied random number generators
...The documentation seems quite
explicit, all the more so because it uses Int32 in places. However, the
code in RNG.c (RNG_Init) says
ns = *((int *) User_unif_nseed());
if (ns < 0 || ns > 625) {
warning(_("seed length must be in 0...625; ignored"));
break;
}
RNG_Table[kind].n_seed = ns;
RNG_Table[kind].i_seed = (Int32 *) User_unif_seedloc();
consistent with the earlier definition of RNG_Table entries as
typedef struct {
RNGtype kind;
N01type Nkind;
char *name; /* print name */
int n_seed; /* length of seed vector */
Int32 *i_seed;
} RNGT...

rnorm
Brian
I've been playing a bit with the Wichmann-Hill RNG. I would prefer to have
normally distributed random numbers and I think I have things generally worked
out to use Wichmann-Hill and then Box-Muller. In the process, I was looking at
R's rnorm.c, but could not figure out what transformation is used in R to
convert uniform rv's to normal rv's. Do you know? It looks like there

Compiling R on Sunos
I'm looking for some help in getting R to compile on Sunos. We run a
collection of Sunos and Solaris machines in the department here. I got
to compile on Solaris 2.5.1 using gcc 2.7.2.2. On my Sunos 4.1.3 (and
I've tried it on Sunos 4.1.4 as well) machines, it crashes during the
compile. I'm using gcc 2.8.1 on there. It gets to this point:
gcc -g -O2 -I../include
