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.
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.

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,

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,

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.

internet2 and proxies
gday R gurus,
I've never attempted to use download.file before on my win2k machine but
this version 1.4 looks exciting. However, I'm not getting something right.
I've passed my R shortcut --internet2 and I can tell it's using the wininet
calls because it's asking about authentication but how do I tell it my
username/password?

postscript preview
gday R friends,
I was wondering if anyone could help me with some graphics issues please.
I'm processing R in batch on redhat6.2 with some graphics to be imported
into msword on NT. For scaling within my doco I want some vector type
graphics. win.metafile doesn't seem to be supported on redhat which gives
me postscript. postscript is ideal but doesn't contain a preview so I

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.

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,

SparseM and Stepwise Problem
I'm trying to use stepAIC on sparse matrices, and I need some help.
The documentation for slm.fit suggests:
slm.fit and slm.wfit call slm.fit.csr to do Cholesky decomposition and then
backsolve to obtain the least squares estimated coefficients. These functions can be
called directly if the user is willing to specify the design matrix in matrix.csr form.
This is often advantageous in large

[LLVMdev] [llvm] r190717 - Adds support for Atom Silvermont (SLM) - -march=slm
Hello Andy,
Thank you for your offer to work together on implementing the your new scheduler on X86. I can start working on this right away.
In case you were unaware, the new Silvermont micro-architecture is only out of order on the integer side. The SSE instructions are still in order, so the current postRA scheduler is very beneficial for code with lots of SSE instructions, such as the ISPC

Use predict.lm
Hi All,
I created a two variable lm() model
slm<-lm(y[1:3000,8]~y[1:3000,12]+y[1:3000,15])
I made two predictions
predict(slm,newdata=y[201:3200,])
predict(slm,newdata=y[601:3600,])
there is no error message for either of these.
the results are identical, and identical to slm$fitted as well.
if this is not the right way to apply the model coefficients to a new
set of inputs, what is

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,

members of my course have encountered the following error message:

Predict using SparseM.slm
Hi,
I am trying out the SparseM package and had the a
question. The following piece of code works fine:
...
fit = slm(model, data = trainData, weights = weight)
...
But how do I use the fit object to predict the values
on say a reserved testDataSet? In the regular lm
function I would do something like this:
predict.lm(fit,testDataSet)
Thanks
