turning off automatic coersion from list to matrix
Hello, I am having trouble understanding how R is coercing between matrices and lists in the following example. I have an aggregate behavior I like: aggregate(a[,"num"],by=list(product=a[,"product"],region=a[,"region"]), sum) Now in reality I have more columns than just product and region, and need to pick different combinations. So I want to abstract this into a

Axis labels
Hello R-experts! When I produce a plot R takes avoids overlapping axis labels in order to maintain readabilty which is great. But now I have written a little custom plot function in which I set my own labels and label positions after generating the actual plot: axis(..., lables=c('A', 'B', 'F', 'G', 'M'), at=mypositions) As you may have guessed: This is

R garbage collection
r-help, The R manual lists two types of memory: transient and user-controlled. If I have transient blocks reachable from the globals only by traversal through user-controlled blocks, will they be correctly preserved? Secondly, what are the ways to mark user controlled blocks as "roots" for the garbage collector, so that transient blocks they reference stay uncollected? So far I

reading large data
Hello, I have trouble using read.table for flat files of larger than about 300MB on windows 2000. Any ideas of how to file a bug report? Is it a known issue? I have three cuts of data, a 1%, 10% and 100% sample in flat text files. The 100% sample is about 350MB. When I read the 1% and 10% files, besides being slow, everything works. RAM footprint appears to increase approximately 2x of text

setuid question
I've got a problem I hope someone can help with. We have a directory on a redhat box where we want anyone who creates a file (usually done with samba access) to have that file be created as if by a special "user" and group.. Now in the smb.privateshares config file we specify force user and force group.. However when we create a file in this directory it shows it being owned by the

logLIk(lme(...))?
Hello, all: I have a dataset with 2 groups. I want to estimate 2 means and 2 standard deviations. I naively think I should be able to use lme to do that, e.g., lme(y~gp, random=y~1|gp, method='ML'). I think I should get the same answer as from lm(y~1, ...) within each level of group. I can get the same means, but I don't know how to extract the within-gp standard

Question about food sampling analysis
Greetings to all, and my apologies for a question that is mostly about statistics and secondarily about R. I have just started a new job that (this week, apparently) requires statistical knowledge beyond my training (as an epidemiologist). The problem: - We have 57 food production facilities in three categories - Samples of 4-6 different foods were tested for listeria at each facility - I need

Groups
Hi All, On one of my servers I have a personal account and root. I disable root for ssh logins and run ssh on an alternative port. When 'scp'ing files I usually scp them up, then ssh in 'su' root and move them to /var/www/html. I can sftp I realize, but what group can I add my personal account to, but not root, so I can sftp in and put the files in /var/www/html? Secondarily

current deployment options
- Have been away from RoR development for a couple of years. - Will be doing a new project soon, starting with RoR 3.1. - This site will be hosted on a dedicated user-controlled server inside their intranet, so this question is not about hosting services. - Expect about 100,000 page views a day, with a bit more spikiness than normal around some shift changes, so provisioning as if for 500,000

Hello, All: ????? What's the status and future plans for R-Forge? ????? I ask primarily because a problem I reported May 15 and 17 via two different channels has yet to be fixed, and it prevents my development versions of the Ecdat and Ecfun packages from building -- because the Windows version cannot find "Matrix";? see below.

OT: Work offer - SAMBA consultant required in Sydney, Australia.
Hi all - sorry for the off-topic posting - just that the list of consultants on the samba site is horrendously out of date!

I just wish I had more time to experiment with it! We have the startings of a good

Intel P35 / quad-core support for HPC applications
Hello all, Does anyone have experience with CentOS and the Intel P35 or G33 chipset? I've googled about and poked in the CentOS forums, but I've generally found questions without responses. I'm part of a university research group doing CFD (computational fluid dynamics). We're incrementally updating our computing power and have been looking at Intel quad-cores and the P35

Extracting variance components from a Manova
I am trying to run a simple nested manova with two levels of nesting, Sires, and Dams within Sires. The goal is to extract the among sires covariance matrix and secondarily, the among Dams within Sires covariance matrix. Both sires and dams are random effects. At present there are four dependent variables, but that may change. This is part of a larger bootstrapping project, so efficiency and

New Mustek UPS model working
Hello, first of all I'd like to thank all the NUT developers for their gorgeous work and for their efforts to make NUT the best and most complete UPS management software I've ever seen (seriously). Secondarily I'd like to help the NUT project as far as my help is needed, I'm not a programmer (by now...) but I would like to help somehow anyway. I have 3 UPS from the same
