regression constraints?
gday R gurus,
I have a multivariate regression for which I want to constrain the
coefficients to be > 0. Is this possible?
I've check the doco and searched CRAN but can't find anything.

printing hclust with k clusters
howdy R friends,
I've searched CRAN but to no avail... I'm trying to use mva's hclust and
print out for say 10 clusters in batch. How do I do this? It's unclear if
I can use cutree.
thanks,

cant find "get"?
howdy gurus,
I was wondering if someone could help me with what looks like a simple
problem.
I found this great function called "get" which allows me to work out my
object name at run time. Unfortunately it's not letting me assign values
with it. What am I doing wrong?
thanks,

R on os390
G'day R friends,
I didn't get any replies on the main list so I thought I'd try with the
experts.
I was wondering if anyone's ported R to os390. If so, are the vsize and
nsize limits the same as other platforms?
I could really annoy those SAS guys then.
thanks,

merge aint merging
g'day R friends,
can anyone please help me with a frustrating merge?
The number of rows of a resulting merge is the smaller of the 2 dataframes
used as input. What am I doing wrong? I'm using 1.1.0 on redhat 6.2

queueing problems
howdy R friends,
I'm new but I used to play with S+ a long time ago. Can someone please help
me with how to approach this?
I have some response time data I want to 'correlate' with other data. I
believe queueing is involved so I need to prove somehow (F test?) that
response ~ exponential(...)
How do I go about this? I cant find exponential in 'nlm' or other
functions.

tapply, sorting and the heap
howdy gurus,
I'm new and green and I was hoping for a tiny bit of your expertise.
I'm running out of virtual memory (heap?) when summing using tapply. I've
already used --vsize=90M on my hpux machine. (details below)
Can I pre-sort or something to prevent my error?
thanks,

lm variable name limit?
gday R gurus,
has anyone seen this lm problem?
When I add 2 bytes to the variable name (via names), lm returns an error.
It's as if there's a limit to the size of the variable names.
Any suggestions?
thanks,

ghostscript errors
gday R friends,
Since I had random errors with ghostscript 6.01 I thought I'd upgrade.
After upgrading to gs6.5 I've had problems. Originally, gs failed
complaining about lack of "__sysconf" in glibc2.2 so I upgraded glibc. Now I
get this. Note that it used to work with gs6.01.
I realise this is probably a ghostscript problem but you never know...
thanks,

Factor Analysis
Thanks to Brian Ripley for the time and effort put into developing the
factanal package for R. I have found it very useful. However, in trying to
replicate some results from previous research, I have run into the need for
a couple of extensions and was wondering if they might find their way into
future implementations.

somebody's stolen my probabilities
gday gurus,
could someone please help me with this one? Can't find it in the doco.
summary of my lm object gives "Pr(>|t|)" but coef doesn't. How do I get
hold of these probabilities within an object? There doesn't seem to be an
appropriate attribute within the object - I was hoping for something like
"my.lm$probabilies".

command history under cursor keys
g'day R friends,
I was hoping someone could provide me with advice as to my dysfunctional
'arrow' keys.
Instead of browsing thru my command history they just move my cursor. What
have I done wrong? My TERM seems ok for other unix apps.
I'm running under hpux 10.20 with R1.0.0

Reading multiple files into R
I want to read data from a number of files into R.
Reading individual files one by one requires writing enormous amount of
code that will look something like the following.

maptools:::dbf.read("wb-02vc.dbf")->dist2

One file open or locked way too many times. How to fix?
A Windows 2000 Server is a member server of the domain. The domain
server is CentOS 4.5 with all updates and Samba 3.0.24 built using the
packaging/RHEL/makerpms.sh script. The W2k server is opening this file
on the samba server.
This problem started several versions of CentOS and Samba ago, and I did
the upgrades thinking it would fix it. It did not.
It seems to be "locking" or

I am running R under Windows 2000.
I am looking for a routine for importing

- dbase files (FOXPRO) into R
and I am looking for time-space models for description and prediction of
Bernoulli-, Binomial- and Poissonvaraibles.
Thank's a lot for a reply.

rsync of file list
Hi All,
I would to rsync data spread of many files from remote site. Each file
may exist in total different location - the path for each file may be
different.
My question is:
Can I do it one single rsync command, giving a file containing list of
paths as parameter, or do I need to run rsync for each file.
I did not find any option doing it in the man page. I tried to play with
