Problem with match.arg() (PR#536)
Full_Name: Kjetil Kjernsmo
Version: Version 1.0.0
OS: osf1
Submission from: (NULL) (129.240.28.227)
Hello again!
This is a follow-up to my message on R-help about a problem with match.arg()
I have a little more on the topic, but not much really.
First, it was not entirely true what I wrote in r-help that I call match.arg()
in my ramp(), because ramp() just calls qamp() with runif() as

The contrast and Design libraries
Dear all,
I have been using the contrast library in my teaching for the last couple
of years and am right in the middle of this year's round. In the last week
R has been updated to version 2.14.0 on our computers. This has had the
unfortunate effect of meaning the contrasts library no longer works, as
the Design library is no longer available. I wonder if anyone has a fix
for this...or

rpois gives a large number repeatedly (PR#439)

Version: 0.65.1

Submission from: (NULL) (129.240.28.172)
I'm experiencing problems with rpois. Occasionally, it draws a very high
number.
Yeah, I know, this is statistics, things like that does happen, but this really
strange because a poisson distribution with a parameter of 3 shouldn't see the
number 1932 very often, but the same,

Developing the UPS side of the UPS-NUT equation (via usbhid)
Things are going along well, but there is one remaining area of confusion...."units". I understand exponents now...it's basically how you pass decimal values. That's easy enough.
But "units"....in other words, I have a voltage I want to put in a report. If I include in the report descriptor the fact that it is actually a voltage, with units of "volts",

manipulating text to generate different formulas to use in nls()
Hello,
In doing a series of non-linear estimations of a function which is a sum of a varying number
of sinusoids, I would like to "autogenerate" the arguments needed by nls() depending on that
number.
For example, when there are two sinusoids:
> nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2), data = some.xy.data,
start = list( mu=some.value0,

Question about Polycom SoundPoint 500
Hi Folks;
I just bought a Polycom SoundPoint 500 off of ebay after having spent
way too much time trying to get updated sip images for our cisco phones.
The phone I bought didn't have an AC power adapter; Could someone
please tell me the volts & amps that the dc plug that comes with the
phone puts out?
Thanks!

Paging unit suggestions
We currently have an Asterisk system that is hooked up to our old paging speakers via sound card, plugged into two amps.
Each amp drives up to 8 analog speakers in each warehouse (we have 2). Both warehouses are around 30k square feet. Both have a large number of printing presses.
The computer system is that is running Asterisk is around 10 years old and starting to fail. I'm looking to

POE Splitters
I've got an interesting situation where I have one cable run from the feed
area to the service area. I have three devices that I need to power at the
service area. Is anyone aware of a device that will take the POE from the
cable run and then allow me to split it to two or three devices at the
service end?
When I search for splitter all I get are the injectors, but I figure someone

Re: Paging using multiple sound cards
Why *wouldn't* I bother? Using $5-$10 sound cards would be a much cheaper,
professional, and more permanent solution than having a couple hacked phones
laying near the PA system. Just trying to keep the setup clutter and problem
free,
as well as as cheap as possible.
I'm not a developer, but I don't think it'd be too much of a pain to program

FXS, Power and Sangoma
Hi
I've a Sangoma A200D with 2FXO and 2FXS. When using it with only
the FXO module, it's all good. But when I put in the FXS module and
connect the power, logs tells me not enough power.

help with package "simsalabim"
I have attached a text file representing the centralized amplitude of a signal, sampled at 30Hz, whose length N = 6922
My goal is to remove the trend. I am using package "simsalabim".
I ran command decompSSA with L = length(Amps)/5
The reason is that I have SSA/MTM toolkit running in Mac/OS. SSA/MTM documentation, relative to SSA, recommends that N/10 <= L <= N/5.

the APU2, which is their current generation board suitable for a router
like this, requires 12VDC up to 1 amp, so tis not suitable for USB power
(5V, up to 2.5 amp) unless you rig up a USB to 12V DC-DC converter.

I think you mean 2.5 *watts* not amps. USB 2.0 and below are 500 mA @ 5 Vdc max == 2.5W. There are nonstandard extensions to USB to allow
