[Rcpp-devel] Setting the R random seed from Rcpp
This would be easier if base::set.seed() accepted a value of .Random.seed
instead of just a scalar integer or, new to R-3.0.0, NULL. If set.seed() returned the
previous value of .Random.seed (NULL if there was no previous value) things
might be even easier. People should not have to know where .Random.seed
is stored.
S+'s set.seed() accepts a value of .Random.seed but does not return the

GHK simulator
Dear R-community,
not to re-invent the wheel I wonder if someone of you
has ever written a function to compute the GHK smooth recursive
simulator to estimate multivariate normal probabilities. See for instance

choose(n, k) for k>n: An inconsistency?
It took me by surprise to find that choose(4,5) delivers
[1] NaN
Warning message:
NaNs produced in: choose(n, k)
If we look at choose(4,5) as the number of ways of choosing
5 objects from 4 I would have expected 0 as result.
Furthermore dhyper(5,4,6,5) does deliver 0 and this essentially
equivalent to choose(4,5)*choose(6,0)/choose(10,5).

Calling R from C - part way there but need a push!
Dear All,
I've read the manual on "Writing R Extensions" and in particular the
part on calling R from C. (Most of the manual is about calling C
from R, not the other way around.)
The good news is that I can now call _some_ R from C, specifically
the R functions which have C header files. However it isn't clear to
me how to call R functions that are written in R. I

Bug in boxplot.stats?
Is this a bug?
>"xx" <- c(50, 79, 120, 78, 90, 100, 78, 80,
+ 90, 80, 60, 39, 90, 85, 140, 100, 80, 80)
> boxplot.stats(xx)$stats
[1] 60 78 80 90 100
> boxplot.stats(0.1*xx)$stats
[1] 7.8 7.8 8.0 9.0 10.0
I suppose the way the numbers in 0.1*xx are internally stored may
cause this problem:

3dim histogram?
Hello all,
I wonder if there is a package including a program to display a 3dim

AW: General Matrix Inverse
Thorsten is right. There is a direct formula for computing the Moore-Penrose
inverse
using the singular value composition of a matrix. This is incorporated in
the following:
mpinv <- function(A, eps = 1e-13) {
s <- svd(A)
e <- s$d
e[e > eps] <- 1/e[e > eps]
return(s$v %*% diag(e) %*% t(s$u))
}
Hope it helps.

Write and Load functions from an external file
Hi All,
Would be grateful,if anyone can answer my queries.
I need to share code. For example, if I am working in C/C++, I would put
some function declarations in .h files that you would include. In PHP, I
would create files with the common functions in them and then "include()"
them. So far, I haven't been able to figure out what the standard practice
is in R.

FWIW, here is a list of base* functions masked** by CRAN packages:

How to create something between a script and a package
(Before starting: I'm a total R noob so please bear with me in case of
any error or faux pas).
Hi,
For a small project, I'm writing a few simple R functions and calling
them from python (using RPy). I'm sharing the code with a couple of
friends, using a subversion server.
Now, I want something like a package, to be able to share functions
between ourselves. Having read a few package

AW: Query: IRR Confidence Intervals
Hi Cristian,
I don't know about a R routine for exact CIs, but I found a function called
"ageadjust" using a gamma distribution approximation some time ago -take a
look at http://medepi.org/epitools/rfunctions/index.html.
That Webpage seems a bit outdated now, but the calculations given in the
ageadjust functions should still work, I think.
Maybe this helps;
regards
Heinrich.
