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.

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".
I was hoping to grab the best t

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,

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?
The help file only talks about user/pw for non

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.

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

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.

one way to write scripts in R
Dear R users,
A colleague of mine asked me how to write a script (an executable text file
containing R code) in R. After I showed
him, he said that after extensive searching of the R archives, he had not
found anything like these techniques.
He suggested that I share these methods to enable others to leverage R as a
better alternative to bash/perl scripts.
So in the interest of giving back to

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?

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?

Instead of browsing thru my command history they just move my cursor. What

Is RoR on SQLServer suitable for a commercial application?
Good Evening,
I need some advice. I am in a position at work where I''ve got the boss
pretty excited about rails. I think I could swing the Next Generation
version of our product to use rails as the platform, but I find myself a
little hesitant to do so until I''ve answered a few issues that I''m hoping
people on this list could help me with.
