R and condor
Hello,
I would be extremely grateful if anyone is able to provide any (rather obscure) advice on using R with Condor. I think I'm following Xianhong Xie's instructions (R News 5(2) 13-15) correctly, but my job just stays held in the queue (for days / months). I've checked condor_status to make sure there are plenty of machines available, but can't see any way to attack the

Testing the equality of correlations
Dear All,
I wonder if there is any implemented statistical test in R to test the equality between many correlations. As an example, let X1, X2, X3 X4 be four random variables. let
Phi(X1,X2) , Phi(X1,X3) and Phi(X1,X4) be the corresponding correlations.
How to test Phi(X1,X2) = Phi(X1,X3) = P(X1,X4)?
Many thanks in advance,
Bernard

Producing "Editable" Graphs for PowerPoint
Hello,
(apologies, I'm not entirely sure whether this question is about R or my
limitations with PowerPoint). I've submitted a paper (which has been
accepted) but the journal now require me to submit graphs that are
"editable in PowerPoint". I would be grateful for suggestions as to
how I should do this.
The best route seems to be to copy-and-paste the figures from the

R package to perform Horn's parallel analysis
I am seeking information on whether anyone has written code to perform
Horn's parallel analysis (a procedure that informs the selection of the
proper number of components in PCA) in R.
Thank you in advance for any help you can provide. Please respond

pairs: altering pch options on upper and lower panel of pairwise scatter plots
Hello,
I can't figure out how to use the upper.panel and lower.panel options in
pairs to alter the label options for either panel independently of the
other.
I would like to be able to show the pairwise scatter plots for the data
as they are (a vanilla pairs plot?) but separately to be able to label
the points according to a factor level. It is easy enough to do this
independently, but I

R and Openmpi
Hello,
We have R working with Rmpi/openmpi, but I'm a little worried. Specifically, (a) the -np flag doesn't seem to override the hostfile (it works fine with fortran hello world) and (b) I appear to have twice as many processes running as I think I should.

Openmpi version 1.1

Rmpi : openmpi and mpi.spawn.Rslaves
Hello,
I'm using R on a 10 blade dual quad core Rocks Cluster, and trying to use Rpmi and snow. I basically wondered if at the moment I ought to install Rmpi against another form of mpi (not openmpi) and wondered whether anyone could pass on any experience.
I'm mainly worried about (a) the R server taking up 100% cpu time (I think this is a known issue with Rmpi and openmpi) and (b)

Cross-compilers versus windows compilers (was optimal win dows R machine)
Good morning,
May I ask a naive follow up to this? Having now been granted limited
rights to use R-windows on a work PC, I wish to set up my home PC to support
compiling packages and so on. I currently have a working Linux set-up at
home, is there any general advice as to whether it would be better to add in
the cross-compilers there or is it better to persuade my home PC to dual

Windows dll compilation (mingw32): how to find R.h and other head er files when sketching short functions
Sorry, this seems like a particularly stupid question, but here goes. It
relates to some "sketching" work I'm doing under Windoze.
I can only get my C code to find R.h and friends if I shift these header
files files and folders into the analogous mingw32 folders. This seems a
rather clumsy way of doing things, and I wondered what I've missed? (I'm

chron is.weekend() function
Hello,
I have a dataset which has fields giving both calendar date and weekday. I
know better functions are now available, but I am still using chron because
of the is.holiday() function and a homemade (even Heath Robinson would be
ashamed) is.daylight() function.
As a check for typos in the data input, I checked that the dates matched the
weekdays. I'm getting some confusing results

Local Moran's I / Getis and Ord and Rousseauw Cluster Algorithms
Sorry for the repetition, unless I've got bad deja vu this questions been
asked before but I couldn't turn up an answer on CRAN. Is there already
any code in existence for local dependence measures such as Moran's I or
Getis and Ord G?
Also, S-Plus has a number of interstingly named Cluster Algorithms based on
some previous stand-alone fortran algorithms (agnes, daisy etc.) which

Random slopes in lmer
Hi
I want to extract the random slopes from a lmer (I am doing a random regression), but are the answers obtained from ranef or coef?
My model is: mod1<-lmer(B~ A +(A|bird), family=quasibinomial)
And I want to obtain a slope for each individual bird but am not sure which output I need and can't find the answer anywhere.
Thanks

what is the difference between destroy and delete in AR
I am not sure what they mean by

calling destroy<http://api.rubyonrails.com/classes/ActiveRecord/Base.html#M000866>(all

Unequal variance ANOVA using gls function in nlme
Hi
I am trying to run an ANOVA on data with unequal variance. I am new to nlme, but to my understanding I need to use the gls function. I have single response variable (distance which is continuous) and the explanatory variable is individual ID (class variable: individuals differ in the variance in their distance values hence the need to using nlme).
So I would create a model

Hi..Guys new plugin again
Hi..
Guys new plugin again
Foreign Key Associations is a plugin that automatically creates
associations based on foreign-keys. The associations are created at
runtime-ie. as your ActiveRecord models are loaded-so they will always
be up-to-date.
For example, given a foreign-key from a customer_id column in an
orders table to an id column in a customers table, the plugin
creates:
