factorial function
Sorry for the stupid question, but is there the factorial function in
R? I tried to find it using help.search('factorial') but got nothing
appropriate.
Many thanks,

problems with ess and xemacs on win32
Hi there;
I have the following problem --- Xemacs cannot
correctly parse a path to file when I load it.
I have the following error, reported by Xemacs:
from ess-parse-errors:
Error in file(file, "r") : cannot open file
`u:US-mortalityjuttalexible.r
While the correct file path should be:
u:\US-mortality\jutta\flexible.r
Any ideas? Many thanks for your help.

Newbie Question/Feature Request
Hi,
I'm working on a plugin for qpsmtpd (a perl smtp frontend) that delivers mail via dovecot's LDA. I can only get mail delivered by writing the email to file, then calling 'deliver -d someone -f someone-else < /path/to/temp/email' All good, expected behavior. A perl snippet:
local $/=undef;
open FH, "< ./demo.mail";
my $stringified = <FH>;

"formula plotting" -> substitute pecularity
This is something between a question and a bug report.

I wanted to plot (.) a formula with "..."

Debian repositories only for amd64
Hi,
Is there any particular reason why the Debian repositories (at
http://download.gluster.org/pub/gluster/glusterfs/LATEST/Debian/ )
only have packages for amd64?
I don't mean to pressure for more convenience; I'm just wondering if
there's any reason to avoid using it on i386.

nnet question
Hello,
I use nnet to do prediction for a continuous variable.
after that, I calculate correlation coefficient between predicted value and
real observation.
I run my code(see following) several time, but I get different correlation
coefficient each time.
Anyone know why?
In addition, How to calculate prediction accuracy for prediction of
continuous variable?

choose() function returning anomalous results (zero instead of one)
Hello,
(Apologies for length, wanted to get all the relevant detail in that I know
of).
I've been having a lot of trouble with some code for an inventory analysis
problem I was doing, and finally came to the conclusion that it appears
that choose() is returning incorrect values. Specifically:

Help: CallerID Name not being sent on outbound PRI trunk
Outbound calls on my Telus PRI aren't taking the Name portion of the
callerID. I've looked at the logs, and it is being set (see below), but
the PRI debug output doesn't show the name being sent anywhere. As a
result, received calls always display from Unknown (or just the number).
Is there some config that I've missed somewhere?

Updating a data frame
Folks,
Updating values in a table is simple in SAS or SQL, but I've wracked my
brain looking for an elegant solution in R to no avail thus far. Certainly
this is a common need that's been solved in dozens of different ways.
Given an initial dataframe nn and a smaller dataframe of updates uu, I'd
like to replace the values in
nn <- expand.grid('a'=1:4, 'b'=1:3)

saving and loading complex objects
Dear Sir:
When I try to save large and very complex recursive objects with some components containing models (such as the output from arima or lm ),
the resulting file sizes increase by 4 meg per save.
example directory:

argentina 12 meg
australia 16 meg
...
Moreover, I am unable to read these file objects back into R.
I note that readBin and writeBin

A doubt about "lm" and the meaning of its summary
I have a conceptual problem (sort of). Maybe there's a simple solution,
maybe not.
First, let me explain the test case that goes ok.
Let x be a (fixed) n-dimensional vector. I simulate a lot of linear models,
y = m x + c + error, then I do a lot of regressions. As expected, the
estimated values of m (let's call them m.bar) are distributed according to a
Student's t distribution.

eigenvalues for a sparse matrix
Hi,
I have the following problem. It has two parts.
1. I need to calculate the stationary probabilities of a Markov chain,
eg if the transition matrix is P, I need x such that
xP = x
in other words, the left eigenvectors of P which have an eigenvalue of
one.
Currently I am using eigen(t(P)) and then pick out the vectors I need.
However, this seems to be an overkill (I only need a single

converting MATLAB -> R | element-wise operation
Why anything but sweep?
The fundamental data type in Matlab is a matrix... they don't have vectors, they have Nx1 matrices and 1xM matrices.
Vectors don't have any concept of "row" vs. "column". Straight division is always elementwise with recycling as needed, and matrices are really vectors in row-major order:
1 2 3
4 5 6
is really
1 4 2 5 3 6
