Doubly Non-Central F-Distribution
Dear Professor
I have read your questions in the website on Doubly non-central
F-distribution. I am looking for source code for evaluating this
function now. I have matlab code but it's only accurate up to the 4th
decimal point. Dataplot is more accurate, but it is not user friendly as
you only can evaluate one function at a time. So I would like to know do
you have found any R code for

R codes for g-and-h distribution
hi!
I would like to ask help how to generate numbers from g-and-h distribution. This distribution is like normal distribution but span more of the kurtosis and skewness plane. Has R any package on how to generate them?
Any help will be greatly appreciated. Thank you so much!
Form,

[PATCH] qemu pcnet emulation fixes
The attached patch to the qemu emulation of the pcnet hardware fixes
several problems. It will now only read and write a transmit or receive
descriptor once. It will correctly handle transmitting frames with more
than two fragments. It will discard oversize frames instead of
corrupting memory. I have tested all the changes I have made and even
seen an improvement in receive performance from

Problem with Weighted Variance in Hmisc
The function wtd.var(x,w) in Hmisc calculates the weighted variance of x
where w are the weights. It appears to me that wtd.var(x,w) = var(x) if all
of the weights are equal, but this does not appear to be the case. Can
someone point out to me where I am going wrong here? Thanks.

R CMD check failing to warn when it should
Hi,
I recently made changes to lattice code which needed changes in many
man pages as well. Before I made the appropriate changes, R CMD check
was flagging most of the problems correctly, except for the man page
for tmd. I have created a toy package that shows this, available at
http://www.stat.wisc.edu/~deepayan/R/tmdprob_0.12-2.tar.gz
This passes R CMD check on R 2.1.0 and r-devel from August

Nonparametric Tukey-type multiple comparisons "Nemenyi" test
I am trying to do a Nonparametric Tukey-type multiple comparison
post-hoc test to determine which groups are significantly different. I
have read the dialogue on this topic from the R-help, and am still not
clear why no statistical packages include this test as an option? Is it
not an appropriate test to conduct on non-normally distributed data? Is
the only option to calculate it by hand

Exposing Zap Channels on Server A to be Used By Server B
Hello All,
I remember there is a way to use two Asterisk servers and allow one to
see a virtual trunk that makes it so server B can use the ZAP channels
on server A.
Does anyone know where I can find this? I am racking my brain trying to
remember the terminology.
It was like creating a 24 channel virtual T1 connection from server B to
Server A that allowed server B to not have any ZAP

how to aggregate T-test result in an elegant way?
Dear all:
Plan 1:
I want to do serval t-test means for different variables in a loop ,
so I want to add all results to an object then dump() them to an
text. But I don't know how to append T-test result to the object?
I have already plot the barplot and I want to know an elegant way to
report raw result.
Can anybody give me some pieces of advice?

TMD card to buy.
Hi Rich, good advice about buying grandstream SIP handsets instead of
using analog handsets though I think you might that using a 30 channel
E1 in Hungary is tough to get.
Can you also explain to him about Channel Banks.

dataplot oen source? (was: RE: FW: re: GUI's for teaching)
IIRC, the license stated in the source code of dataplot is rather
restrictive. I don't think one is allowed to use the source as can be done
with GPL code.
Cheers,

Exposing Zap Channels on Server A to be Used ByServer B
Robert,
Essentually I want to be able to have Server B dial the extensions
connected to server A as well as route calls to the outbound route on
Server A.
Server B will have little to no knowledge of what is on Server A. I
just want it to dump the calls off.
For some reason I keep thinking this was a PRI type of thing. Like
there was a module that loaded up as a fake PRI that your

Data Frame Search Slow
Hey All,
So - I promise to write a blog post on this topic and post it somewhere on
the internet once I get to the bottom of this. Basically, the set-up to the
problem is like this:
1. I have a data frame with dim (2547290, 4)
2. I need to make SQL like lookups on the dataframe. I have been using the
following sort of syntax:
a.dataframe[a.dataframe[[column_index]] %in% some_value, ]

FW: re: GUI's for teaching
Have a look at the GUI on dataplot, NIST's plotting software. It is implemented in tcl/tk. The site states it is "public domain software" -- open source? I can't find anything about the license. In any case...

how to get a line plot before/after treatment
Dear R help-list reader,
I would like to generate a plot which compares to states in a patient
treatment, before and after. for this reason I have generated a vector

and
after<-c(20,10,20,60)
the first element in "before" corresponds to the first element in "after".
I would like and generate a dotplot with

Bounding or constraining parameters in non-linear regressions
Dear R-Users,
Being an engineer and not a statistician, my desired course of action may
either be impossible or very simple.
I am attempting to fit a non-linear model to some measured data. One term in
the model contains a square-root, but in the course of regression, this term
turns negative and an error occurs. I started using Micrsoft's Excel Solver,
and then I turned to NIST's

I have a problem with the log2 function
Dear R users,
according the help(log), the function
log2(x) should give the natural logarithm of x.
I expect in case of x=2 to to get 0.6931, however, R gives me 1 as a result.
Similar, logb(2,2) gives 1 again.
I'm wondering if I have missed something ?
Yours
Frank
