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,

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,

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.

handling dates
howdy R friends,
Can anyone help me with converting a ''unix'' date (seconds since 1970) into
something readable?
There doesn''t seem to be anything in the ''date'' package and the prospect of
calculating this myself doesn''t excite me.

regression constraints?
gday R gurus,
I have a multivariate regression for which I want to constrain the

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

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.

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

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...

command history under cursor keys
g'day R friends,
I was hoping someone could provide me with advice as to my dysfunctional

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

I'm running under hpux 10.20 with R1.0.0

Getting betas in lm
Howdy,
is there a simple way to get beta weights from lm? So far I've done
z-transformations of the variables before using them in lm.
I also wonder whether there is a function to calculate variance with
n instead of (n-1)?

I'm still getting used to R's scoping. I've run into the following situation
value=0
thefunction <- function() print( value )
somefunction <- function() { value=99; thefunction() }

now, I understand that somefunction() returns 0 because thefunction() was
defined with value=0 in its parent envrionment, it dosent look at all in the

Partial Derivatives in R
Quick question:
Which function do you use to calculate partial derivatives from a model
equation?
I've looked at deriv(), but think it gives derivatives, not partial
derivatives. Of course my equation isn't this simple, but as an example,
I'm looking for something that let's you control whether it's a partial or
not, such as:
somefunction(y~a+bx, with respect to x,

how about a "<p-" operator?
I was cursing Matlab again today (what else is new) because the default
action for every Matlab command is to spew the result to the console,
and one must remember to put that darn ";" at the end of every line.
So I just wondered: was there ever a discussion as to providing some
modified version of the "<-" and "->" operators in R to do the reverse?

Combining all possible values of variables into a new...
I'm trying to create a new column in my data.frame where subjects are categorized depending on values on four other columns. In any other case I would just nest a few ifelse statements, however, in this case i have 4*6*2*3=144 combinations and i get weird 'context overflow' errors. So I wonder if there is a more efficient way of doing this.

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

a couple of extensions and was wondering if they might find their way into
future implementations.
