change directory?
Please pardon a novice use question.
Is there any way under the Win32 version of R (1.3.0)
to change the working directory from the GUI command
line? I see the "Change dir" entry under the File
menu, but haven't found a corresponding command.
Thanks in advance,

for loop question
In the windows version of R (1.3.0) is the following a bug, a
known problem, or expected behavior:
> for (i in 1:2) {
+ for (j in i+1:3) {
+ print(j)
+ }
+ }
[1] 2
[1] 3
[1] 4 ????
[1] 3
[1] 4 ????
[1] 5 ????
>
Conversely, the following behaves as expected:
> for (i in 1:2) {
+ k <- i+1
+ for (j in k:3) {
+ print(j)
+ }
+ }
[1] 2
[1] 3

unary "-" on logicals
"An Introduction to R" says that arithmetic operators
coerce logical vectors to numeric vectors. This doesn't
seem to be true for unary "-" however:
> x <- 1:10
> p1 <- (x > 5)
> p2 <- (-p1)
> is.logical(p2)
[1] TRUE
> is.numeric(p2)
[1] FALSE
Since "==" always does binary comparison, this can lead to
some bizarre behavior:

if/else at 1.3.1
Under NT with 1.3.1
if (x == 1) {
cat("Saw x=1\n");
} else {
cat("Saw x!=1\n");
}
works as expected, but
if (x == 1) {
cat("Saw x=1\n");
}
else {
cat("Saw x!=1\n");
}
is currently giving me a syntax error on the "else" line.
Apparently the parser considers the if statement to have
ended as soon as it sees first closing brace, unless

problem installing quadprog
When I try to build/install the quadprog package under R1.50 and NT4
it seems to have trouble finding blas routines. I'm currently using the
generic blas routines, rather than ATLAS or some other tuned implementation:
> Rcmd INSTALL d:/temp/quadrprog
...
gcc --shared -s -o quadprog.dll quadprog.def quadprog.a quadprog_res.o -Lc:/a

Followup on quadprog installation
Oops... just realized there were a couple mistakes in the question
I posted regarding installation of quadprog:
1) The gcc command line is shown wrapped to the next line.
Please ignore this.
2) In addition to adding a -Lc:/apps/rw1050/bin option to the
command line, I also added -lRblas.
Thanks,

cannot allocate vector
Hi,
I'm having trouble with glmmPQL.
I'm fitting a 2 level random intercept model, with 90,000 cases and about 330 groups. I'm unable to get any results on the full data set. I can get it to work if I sample down to about 30,000 cases. But for models with N's much larger than that I get the following warning message:

aov help
Please pardon an extremely naive question. I see related earlier
posts, but no responses which answer my particular question. In
general, I'm very confused about how to do variance decomposition with
random and mixed effects. Pointers to good tutorials or texts would
be greatly appreciated.
To give a specific example, page 193 of V&R, 3d Edition, illustrates

openssh on HPUX 11i
In case this hasn't already been reported or discussed...
It took some doing for me to get openssh working on HPUX 11i.
The fixes are quite simple. First, one must have the IPV6
package installed:
em 512# swlist -l product | grep IPV6
IPV6AA A.01.01.5D IPv6 11i product
Second, I have to edit config.h to undefine HAVE_GETADDRINFO.
Without IPV6, ssh can't connect

GLMM question
Hi
I'm using lme4 to do random effects modelling.
I keep getting the following error message:
Error in "EMsteps<-"(*tmp*', value = control) :

I get the error when I include more than one random effect in the model, sometime I'm able to get two. I've looked into the variables that cause the problems aren't highly correlated,

R bioconductor agilent aCGH analysis
Hi,
I would like to analyze some agilent aCGH copy number files. As a start, I
would like to normalize this data. I don't know what is the standard way to
do this. Which package is the standard one that people use for this
purpose? The chips that I am looking at are the agilent sure print 1M
(G4447a) array and a custom chip with similar format. My raw data is a text

swat on red hat 7.2
Hi,
I'm having a minor issue with swat on red hat 7.2. It won't let me make
any changes to the samba server (adding shares, printers, and global
definitions). The buttons to access these simply don't exist. I can view
status, but I can't make any changes (not even restart the daemons).
This works fine on my Debian system. The only real difference that I can
think of is inetd

Problem using -v within rsync transfer.
Hello,
We have used rsync on a mirroring application successfully for just over a
year. After our upgrade to 2.4.6, however, the process started failing
about 50% of the time. The nature of our failure was that the rsync
processes on the remote system would die with no error message, leaving the
local system processes hung. I have netstat and trace output for available
if needed, but I see
