setting the seed in standalone code using Rlib
Hi,
Is the below -- setSeed -- an okay way to set the seed in standalone
applications making use of Rlib? It seems to work as expected. Is
there a better way to do it? (I'm also looking at do_setseed but am
unsure what to supply as op. findFun("set.seed", R_GlobalEnv)?) Thanks
much.

setseed() works well
I tried the following comm in Linux(Ubuntu), It works well:
>set.seed(43);runif(3):rnorm(3)
>set.seed(43);runif(3);rnorm(3)

Take variables in data.frame and create list of matrices
Hi,
I have this sample data below and would like to create a list of matricies.
setseed(1254)
id <- c(1,1,1,1 ,2,2,2)
o <- as.factor(c(1:4, 1, 3, 4))
r <- rep(.5, 7)
v <- rnorm(7)
s <- rnorm(7)
dat <-data.frame(id, o, r, v, s)
dat
#> dat
# id o r v s
# 1 1 0.5 0.7024631 2.0813672
# 1 2 0.5 -0.5541955 0.1095156

RE: timeslab
...;
> So which is which, what's the difference? ....
Sorry if this wasn't self evident:
timeslab-1.0.tar.gz == timeslab-1.0-0.tar.gz
and thus timeslab-1.0-1.tar.gz is the latest version.
Incidentally, if someone of the core team could let me know how to deal
with the 'setseed' issue. Why is R deviating from S in this point?
Best,
Bernd

Random numbers
Hi All.
I have R code whose functionality is being replicated within a C+
program. The outputs are to be compared to validate the conversion
somewhat - however (as is always the case) I have stuffed my code with
random number calls.
Random uniform numbers in C+ are being produced using the (Boost)
mersenne-twister generators (mt11213b & mt19937) - which is the default
type of generator

R-alpha: set.seed(.) [was 'compatibility']
...generate numbers from a new portion of the overall cycle.
The intent being that for ANY i,j (i!=j) set.seed(i) and set.seed(j) would
choose ``distant'' parts of the periodic cycle.
Unfortunately, we don't know what exactly happens in
the S-plus code for set.seed(i), namely, .C("setseed", as.integer(i))
However, I have found out the following which should suffice :
1) Only .Random.seed[4:6] are varyied by set.seed, i.e.,
after set.seed(i), .Random.seed always is
1 2 3 4 5 6 7 8 9 10 11 12
