Improper coding for an offset in vglm()?
Hello R-help.
I believe I may be coding the offset incorrectly in my formula. I am
testing significance between different group pairings using the VGAM
package. My data are zero-truncated and poisson-distributed and
overdispersed, so I'm using the posnegbinomial function in vglm (code
below). I've spent a very long time working out this model and am pretty
sure it's the best for

extracting groups from hclust() for a very large matrix
Hello,
I'm having trouble figuring out how to see resulting groups (clusters)
from my hclust() output. I have a very large matrix of 4371 plots and 29
species, so simply looking at the graph is impossible. There must be a
way to 'print' the results to a table that shows which plots were in
what group, correct?
I've attached the matrix I'm working with (the whole thing

summing and combining rows
Hello,
I have a data set that needs to be combined so that rows are summed by a
group based on a certain variable. I'm pretty sure rowsum() or rowsums()
can do this but it's difficult for me to figure out how it will work for
my data based on the examples I've read.
My data are structured like this:
Plot SizeClass Stems
12 Class3 1

count() function
I keep expecting R to have something analogous to the =count function in
Excel, but I can't find anything. I simply want to count the data for a
given category.
I've been using the ddply() function in the plyr package to summarize
means and st dev of my data, with this code:
ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise,

Teles PCI and chan_capi, possible ???
Hello!
I'm curently using * with two old Teles PCI card (wich, btw, were hard to
install and make good use of) with ISDN4Linux.
The sound quality is simply perfect.
However both dialing in and out through the ISDN line, there seems to be a
_little_ bit of echo that eventually gets on your nerves !
Also the echo seems to get a _little_ bigger after a minute or so into the
conversation.
Now,

NEWBIE - No Audio on ISDN BRI (Teles PCI)
Hello, folks! This is my first post here.
I installed Asterisk from scratch and after reading a lot of information on
voip-info and this mailing list I was able to get started.
I can make sip-to-sip calls (just on a basic extentions structure, let's say
for beginners) but now I'm trying to make this system works with my Teles
ISDN BRI PCI card.
I can make and receive calls through X-Ten

We have thousands of U ISDN interface phones
Since the largest regional ILEC in Brazil completely stopped taking new BRI
ISDN customers and started heavily incentiving their existing customers to
migrate over to ADSL (regardless if what they need is voice or data), we have
thousands of ISDN phones collecting dust.
Is there any network side U cards that will work with Asterisk, so we can turn
those phones into useful things ? I'm

asterisk 1.2 & hisax teles 16.3 isa
Hi
I was using asterisk 1.0.7 until now. For my connection with the PSTN I used
a good old isa hisax teles 16.3 isdn card. Now while compiling 1.2 I
nothiced that i4l and chan_modem is no longer supported? Is there any way of
getting my good old ISA card to work under 1.2?
The docs keep saying use misdn, capi, etc from now on. But I don't think my
card is CAPI capable

How to let ZAPHFC work with and act on different incoming MSNs?
Hi all,
I'm struggling some time now with this problem. Googling and searching
on this topic did not deliver the answer yet, so my last hope is this
list.
Analogue to the things which are possible with modem.conf, where I can
configure the MSN's to act on, I would like to have similar
functionality.
This is the idea:
I have 1 ISDN line, it can be reached by 4 different MSN's.

The outgoing E1 is connected to an pri_net port from my *.
The incoming call will dail out to a h323 soft phone like openphone or
sjphone or just netmeeting.
The call will be conneted, but i don't hear any sound, from no one of the
both sides.
Can somebody help me?
Thanks,

Very high delay
Hi
I'm using a Teles ISDN passive card configured in modem.conf.
when i make call from my sip client (xtex x-pro) to the external world i have more than 1 second of delay and echo very.
There is some tuning to do?
The performance is better with an active ISDN card or CAPI compatible driver?
thanks

question on staRt package
Dear Sirs,
I have been using the package staRt but it has disappeared from the latest R versions. I emailed the author but he never replied. Is it possible to let me know if that package has been removed or if it has been replaced by another or what happened? The latest version is 1.1.12.
I would like to know if I can keep using it or not. If it has been permanently removed, I should look for
