Equivalent to a BY command in SAS
Hi,
I'm very new to R and absolutely love it. Does anyone know how to use
something in R that functions like a BY command in SAS?
For example, let's say you have a variable x, and you want to see the mean.
Easy...
> mean(x)
But what if you want to see the mean of x conditional on another discrete
variable? My best attempts so far are something like...
> mean(x, y_cat=1)

Legality Question about R's Open Source GNU GPL License
Hi,
I use R at home, and am interested in using it at my work company (which is
in the Fortune 100). I began the request, and our legal team has given some
gruff about the open source license. Not boring you with the details here,
but I used some info on gnu.org as a rebuttal, and someone at the company
replied that the generalities of GNU GPL may differ from R's specific GNU

outer function problems
I'm pulling my hair (and there's not much left!) on this one. Basically I'm
not getting the same result t when I "step" through the program and evaluate
each element separately than when I use the outer() function in the
FindLikelihood() function below.
Here's the functions:
Dk<- function(xk,A,B)
{
n0 *(A*exp(-0.5*(xk/w)^2) + B)

recursive function help
I'm trying to implement a recursive function using integrate, and I
suspect I need a Vectorize somewhere,
but I can't suss it out. Any help would be appreciated. I've tried
traceback() and various debugging ideas to no avail (most likely due to
my inexperience with these tools.)
Here's what I have.

[PATCH] Report last-modified time of hive root and nodes
The infrastructure for modified-time reporting has been essentially
unused. These changes report the registry time by treating the
time fields as Windows filetime fields stored in little-Endian
(which means they can be treated as a single 64-bit little-Endian
integer). Some of the code changes necessary include:
* Exposing the hive_h structure in the hivex header file (via
generator.ml)

Corrupted index file
Hi,
I've been wondering for a while if reiserfs is dovecot+maildir safe or
not. I get this too often (and my imap session gets disconnected):
Jun 9 08:42:32 sun imap(nk): Corrupted index file
/home/nk/Maildir/.INBOX/.imap
.index: UIDVALIDITY changed in uidlist
This happens always when a new mail arrives in maildir.
It's a Fedora Core 2 box running dovecot-0.99.10.4-4 (redhat) package.

hivex lib: Add function hivex_node_num_children
Hello,
I've been working on a graphical registry hive editing tool in Qt
using the hivex C library.
While creating it, I noticed that in order to determine if an
expansion element should be shown on a node, you have to determine if
a node has any children.
Currently, in order to determine if a node has any children, you must
find every child with hivex_node_children, which is a relatively

Problem starting wine
Hi,
I am a newbie here. I am trying to run wine on Mandrake 7.1. I get the
following error:
Warning: could not find wine.conf [Drive x] entry for current working
directory /home/nk; starting in windows directory.
Invalid path 'c:\windows' for temp directory
Perhaps you have not properly edited or created your Wine configuration

This is either /etc/wine.conf or $HOME/.winerc

[PATCH] Add a cache for iconv_t handles to hive_t
It was brought to my attention that dumping a registry hive causes a
lot of time spent in disk I/O activity because iconv_open() and
iconv_close() are called for every key. Every iconv_open() call causes
/usr/lib/.../gconv/$ENCODING.so to be opened and mapped.
The iconv_t handles are now cached in the hive_h struct; they are
opened on-demand and re-used.
On my ~10 year old Lenovo T60, I have

to the hivex ABI, to report the amount of hive space used for each
stored structure.

Combinatoria
En relación con lo que comenta Carlos, por ejemplo para el caso de las Variaciones sin Repetición, puede ser instructivoenseñar como se construye como por ejemplo:
VsinR <- function(m, n){ return (factorial(m)/factorial(m-n))}
VsinR(9,3)

[Matlab] Need help on ARIMA and Matlab
Hi, I have to forecast some value of a time series using an ARIMA(5,1,3)
model.
I saw in Matlab there isn't a function for ARIMA models because ARIMA
models are a type of Box-Jenkins models. But how to set parameters?
In the Box-Jenkins models
m = bj(data,[nb nc nd nf nk])
How to set nb, nc, nd, nf and nk in order to have an ARIMA(p,d,q) model?
Thanks
