regression on a matrix
Hi -
I am doing a monte carlo experiment that requires to do a linear
regression of a matrix of vectors of dependent variables on a fixed
set of covariates (one regression per vector). I am wondering if
anyone has any idea of how to speed up the computations in R. The code
follows:
#regression function
#Linear regression code
qreg <- function(y,x) {
X=cbind(1,x)
m<-lm.fit(y=y,x=X)

New snapshot: network stack cloning / virtualization patches
Network stack cloning patches allow for multiple fully independent network
stacks to simultaneously coexistst in a single FreeBSD kernel. Combined with
jail-style separation between user processes and with proportional-share
extensions to the standard BSD CPU scheduler, the patched kernel can
efficiently provide isolated and controllable pseudo virtual machine
environments. The patches

compiling kernel without -O
Hello!
Is it possible to compile kernel without '-O' option?
When my COPTFLAGS=-O -pipe, it compiles fine. When I change
COPTFLAGS=-pipe, it breaks:

sing-prototypes -Wpointer-arith -Winline -Wcast-qual -fformat-extensions -ansi

PATCH: Forcible delaying of UFS (soft)updates
Here's a patch against 4.8-RELEASE kernel that allows disk writes on
softupdates-enabled filesystems to be delayed for (theoretically)
arbitrarily long periods of time. The motivation for such updating
policy is surprisingly not purely suicidal - it can allow disks on
laptops to spin down immediately after I/O operations and stay idle for
longer periods of time, thus saving considerable amount

Phantom nulls in usbdevs.h during 9-STABLE kernel build
We are seeing strange problems building the kernel on 9-STABLE. The
problem is intermittent and will go away if we build enough times in a row
without making any changes.
The problem seems to be that the usbdevs.h file (which appears to be
automatically generated) gets random NULL bytes in it.
This occurs on multiple servers with ECC RAM and ZFS filesystems (sometimes

kernel: locore.s doesn't assemble (fillkpt, $PAGE_SHIFT, $PTESHIFT)
since august 8th, 2003 the kernel on my i386 pentiumIII won't compile.
the problem arises in locore.s with the definition of the constants
$PAGE_SHIFT and $PTESHIFT used in `shr' and `shl' instructions within
the macros `fillkpt' and `fillkptphys'.
i've tried to cvsup(1) RELENG_4 and RELENG_4_8 every day for over a
week now, but kernel builds (as part of a buildworld)

(OT) rfc1948 question
Hi, folks @ freebsd-security.
First, I am not sure if this is apropriate topic for that list, so
sorry, if it is not.
Some time ago I have read rfc1948 (protection from blind TCP spoofing)
and became interested in the way how it is implemented in FreeBSD.
After some googling (BTW if you like Google you might be interested in
this: http://register.spectator.ru/img/bart.gif ), I found this:

This looks like a very cool feature addition to RELENG_7! Are there
any performance penalties that you know of with this built in ?

em(4) + ALTQ broken
I'm having problems getting PF + ALTQ to work on em(4) interfaces under
8.0-RELEASE. Kernel was rebuilt with the additional options necessary for
ALTQ and what not. Same basic configuration works fine under 7.2-RELEASE.
Basically, the queues create successfully but running a pfctl -vsq shows a
zero packet/byte count for all queues, even the interface's root queues.

dyn.load in linux: missing libraries?
Hi,
I've just about got myself transferred from windowsXP to Linux (Mepis
3.3.1-1). I've got R 2.1.1, emacs, and ess running from the debian
repositories. Of course, there is a hitch. I have a bit of C code in one
of my personal functions. I have, apparently without problem, been able
to compile it using R CMD SHLIB, but when I try to dyn.load it I get the

Question about Running C code from R
Dear R-devel,
Apologies for sending what is probably a very simple question to R-devel: I am definitely missing something very simple and can't work out what it is. I've been trying to find the problem here for about a month and need some help!
I am trying to work out how to run a C program from an R script. Rather than try the C program directly, I'm trying to get a much simpler

Newbie - missing cursor and unresponsive to input
Hello everyone,
I have just discovered wine and have to try it,
but I am running into problems that I can't google my way out of.
