constructing nxn matrices involving calculations& conditions based on other tables
Dear R-users,
I am having trouble constructing nxn matrices involving calculations&
conditions based on other tables.
Below I describe a simple example of what I am trying to do:
Given the Table A (n x m):
Species1
Species2

Hello
As I'm beginning to write functions, I decided to have my personnal R library

The library file itself is at /home/fred/R.Lib/MyStuff/R/MyStuff
evrything seems ok since

ipmitool and CentOS 7
On Dells running CentOS 6, we could use this command
ipmitool delloem lcd set mode userdefined "$(uname -n | sed -e 's/\..*//' )"
to set the little LCD screen to display the system name, In the latest
sevens, it fails, and gives me usage for the command... which displays
exactly that syntax.
Anyone have a clue?

user-defined spatial correlation structure in geeglm/geese
Dear all,
We have got data (response and predictor variables) for each country of the
world; I started by fitting standard GLM and tested for spatial correlation
using variogram models (geoR) fitted to the residuals of the GLM. Spatial
autocorrelation is significant. Therefore, I think about using general
estimation equations (geeglm or geese in geepack) allowing for residual

R vglm new family writing: mix Poisson/multinomial
Hi dear R users,
1)
I would like to know if there is a simple way to define a vglm family which
would be a mix of poisson variables and bernoulli variables (0/1 response)
for idea this would be invoked like this:
vglm(...,family=mixpoissonmultinom(npoisson,n01response))
where the n's give the number of each type of response.
2)
and a simpler question : How to use constraints in rrvglm?

Drawing a tree in R
Hi,
I've been trying to make use of the dendrogram class to plot a tree. However, my attempts have failed so far because I'm not sure how to build up the nested list. (where do I have to store the nodes?). The tree I want to be drawn is like this: in the form (node, left child,right child) (root,(n1,1,(n2,2,3)),4)
If it is not easily possible to draw a tree with the help of the

rbinom
I have the following code (which I did not write) that generates
data based on a logistic model.? I'm only getting a single record
with y=1.? It seems implausible that in 50k cases that have a
single y=1.? Does that ring alarm bells for anyone else?

Fitting data to chi-squared or noncentral chi-squared distributions
Does anybody have any experience fitting data to the non-central chi-squared or chi-squared distribution? I am trying to fit some data to this distribution but there is error after error.

[LLVMdev] Improving Garbage Collection
For the past few years, my group in Intel Labs has been working on a project similar to LLVM and C--, and perhaps our experience in handling roots and stack walking could be useful in deciding how LLVM should evolve in the GC area. Our project is called Pillar (you can see our paper "Pillar: A Parallel Implementation Language" in Languages and Compilers for Parallel Computing 2008 for a

quasipoisson, test="F" or "Chi"
Hi,
Please can someone tell me if this is correct for significance tests on count data;
1: If overdispersed, use quasipoisson, drop1(model, test="Chi"),
2: If not overdispersed, use (poisson or quasipoisson), drop1(model, test="Chi").
Thanks for your time,
Martin.

Chi-Square test
Hello all,
I am doing a Likelihood Ratio (LR) test in my simulation and I have a vector
LR values (each with 1 degree of freedom) at the end of my simulation.
Can anybody tell me how I can write a 'R' code which gives me the p-value
for each of those LR values.
Thanks

partitioning chi-square statistic (g squared)
hi all -
is there a package or library that contains a function for partitioning the
chi-square statistic of an I X J contingency table into its respective
independent parts?
i looked around for this, but i didn't find anything. perhaps there's
another name for this sort of analysis? i know it as "g-squared".
thanks,
chris.

Scale-Inverse Chi square Distribution
Dear all,
sorry to bother you but I was looking for the "scale Inverse Chi square distribution" and I could not find it!
If I remember well , when X~Scale-Inv-Chi-Square (a,b) then X~Inv-Gamma(a/2,a*b/2) but with the shape, scale and rate parameters I always get confused!
Any suggestions?
Thanks a lot for your prompt reply.
Best regards,

Enright/Chi-square periodogram / periodicity
I am trying to compute the periodicity of a time series.
I would like to know which function in R does it.
Also, how do I plot a Enright / Chi-square periodogram using R ?
( Enright, J.T., 1965, Journal of Theoret. Biol. 8,426-468)
Greatly appreciate your help.
Thanks in advance,

Fitting chi-squared distribution
Dear all,
I have a question regarding performing test if the data fits chi-squared
distribution.
For example, using ks.test()
I found in the examples how to fit it to gamma or weibull
x<-rnorm(100)
ks.test(x, "pweibull", shape=2,scale=1)
for the gamma, pgamma can be used
But I cannot find the value of this second parameter for the chi-squared
distribution.

calculate correlation effect size using contrast analysis for an omnibus Chi-square test statistic
I am looking for an R package with which one can calculate an effect size for a set of contrasts given an omnibus chi-square test statistic (more than 1 degree of freedom). Is there such a package? Presumably, it would implement the procedure (or something like it) described by Roznow and Rosenthal 1996 Psychological Methods 1: 331-340.
many thanks!
