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 boot windows

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 using the gcc -02

Incompleteness in Lattice documentation (was Re: lattice question: adding slopes to bwplot)

It made sense indeed: enough to discover the panel.linejoin function which does what I was looking for. <error here> I also understand now why I didn't find this, and associated, routine:

CRAN task view: Multivariate
Hello, I've assembled a Multivariate ctv (with a lot of help from Achim Zeleis, who has now posted the view on CRAN). I'd be grateful for comments regarding missing packages / functions. Opinions on the organisation of the view would also be appreciated, as well as having any errors pointed out. I've adopted a rather broad and vague definition of "multivariate", which may

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

MAX TNT Question
Hi ALL, I'm using this TNT to front-end an asterisk cluster, working pretty well so far. Some T1's are inbound from PSTN PRI's and others are Outbound to PSTN PRI's. Specifying what traffic to send out what PRI is pretty easy, we have unique trunk numbers assigned to specific T1's or groups of T1's, so when I send SIP traffic to the TNT, I prepend the dialed call with

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.

Is there already any code in existence for local dependence measures such as Moran's I or Getis and Ord G?

Reformatting dates using chron

Using the following code, I got most of what I want, dts <- seq.dates("01/02/1998", "01/10/2001", by="day") dts <- dts[!is.weekend(dts)] a sequence of weekdays only (no weekend dates), with first observation appearing as 01/02/98 and the last 01/10/01.

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

Find out the day of week for a chron object?
I know that this is correct: library(chron) x = dates("01-03-04", format="d-m-y", out.format="day mon year") print(x) It gives me the string "01 Mar 2004" which is correct. I also know that I can say: print(day.of.week(3,1,2004)) in which case he says 1, for today is monday. My question is: How do I combine these two!? :-) I have a
