Only BUILTIN accounts working on 2k3 AD
Hi, I have partially got Samba on Fedora Core 1 talking to AD on 2k3.
I've been following Samba 3 by example, (which is excellent btw -
http://www.samba.org/samba/docs/man/Samba-Guide/)
I can access my shares by "administrator", I guess becuase it's a built in
account. I have other groups on the AD server, and I also have users :-)
Does anyone know where I may have mucked

Error message for infinite probability parameters in rbinom() and rmultinom()
Dear all,
Using rmultinom() in a stochastic model, I found this function returns an error message 'NA in probability' for an infinite probability.
Maybe, a more precise message will be helpful when debugging.

inspect now available?
Dear All,
I am wondering if R now has a similar function to inspect in Splus? Someone post this question in 1999 and the answer was no, and I am wondering if this function has been developed in 2003?
Thanks for your attention.

RE: rmultinom
Dear newsgroup,
There was a recent post suggesting the incorporation of a standard
rmultinom(...). This seems like a good idea, but I wasn't sure about basing
this on tabulate( sample( ...)). Despite the attractive succinctness, this
could be very slow and use lots of memory if n or size is large. Instead,
I've tended to use a loop over the boxes of the multinomial, taking
successive

R project global options file
Hello R-help,
I currently have R-project 3.4.2 and R-studio 1.1.383 installed on some of our universities computer labs. Since the installation of Visual studio the default version of R installed has changed to the version installed by VS. Users can change the default R version: found in R studio global options but users need to do this every session. Is there a file or

rmultinom
Hi
Can anyone help me? I am not an experienced R user (or statistician!). If I
use rmultinom to generate random outcomes of a multinomial distribution, how
do i use these in a way to help conduct an exact chi-squared test?

aggregating data
Hi,
I am interested in using the cast function in R to perform some aggregation. I did once manage to get it working, but have now forgotten how I did this. So here is my dilemma. I have several thousands of probes (about 180,000) corresponding to each gene; what I'd like to do is obtain is a frequency count of the various occurrences of each probes for each gene.
The data would look

rmultinom.c error probability not sum to 1
Dear all,
I have a questions regarding using the c function rmultinom.c.
I got the following error message "rbinom: probability sum should be 1, but is 0.999264"
Which is thrown by:
if(fabs((double)(p_tot - 1.)) > 1e-7)
MATHLIB_ERROR(_("rbinom: probability sum should be 1, but is %g"),

I understand my probabilities do not sum to one close enough. I

RE: rmultinom
Hi Mark:
I had also used sample and tabulate for generating multinomial and found it
to be quite slow. So I had written a multinomial random numbers generator
based on the GENMUL subroutine from "ranlib", which in turn is based on the
algorithm from Luc Devroye's book on "Non-Uniform Random Variate Generation"
You may want to compare this with your hybrid algorithm and

rmultinom() -- how \\ via own C code?
I've had a need for multinomial "random number generation"
occasionally. And other people too.
The following code is currently in the

Tru64 Samba queue display problem
Hi,
I'm having problems with the queue on a Tru64 box running Samba 2.2.4.
When the queue is viewed from a client machine it displays a print job with
fields equivalent to the first line the lpq command outputs.
For example, lpq returns:

cut in R
Dear All,
I wonder whether it is still valid to use the following R code for cut. All I have done is changed:
if (is.na(breaks) | breaks < 2)
to:
if (is.na(breaks) | breaks < 1)
so that it covers interval of 1?
It seems okay for my purposes but I am not sure why R specifically does not allow break<2 to happen.
Steve.
