Hi list. I''m running Xen 4.0.1 on Debian. I''m trying to live resize a block device : - I have a arbitrary block device in my dom0 (/dev/mapper/vm-vol42). - I start a PV domain with that device as a disk (disk = [''phy:/dev/mapper/vm-vol42,xvda,w'']). - I resize vm-vol42 in the dom0 (adding size only) - the dom0 sees the device''s new size. -

Hi out there Is there a way to get the estimated coefficients in a logistic / Cox regression without having to specify a 'formula' but by only giving the model matrix? Example for Cox regression: ## predictors n <- 50 q1 <- rnorm(n) q2 <- rgamma(n, 2, 2) Z <- cbind(q1, q2) ## response ttf <- rexp(n) tf <- round(runif(n)) ## compute estimates res <- coxph(Surv(ttf,

Hello, has anybody written a function to plot density ellipses (95%, 99% or anything) in a scatterplot? I found nothing in any package, nor in the list archives. There does seem to be a contributed package "ellipse" for S-Plus (on S-Archive), but it does a lot more than what I would need. Still, if anybody ported it to R, I'd be grateful for a link. I'm a bit afraid to try the

Hi list, I have hacked together a small script to generate an ActiveRecord model from a DBDesigner 4 (fabForce.net) model file.

Hello List, I have a production machine with very low ram (Xen Virtual Server) that runs mysql and lighty->pound->mongrel (2 instances). About once a day, one of the mongrels just locks up, leaving that in its log files: *** glibc detected *** /usr/bin/ruby: free(): invalid next size (fast): 0x0a744780 *** That process (mongrel) will stay locked, not answer any connections anymore and

Hello, does anyone know of a quick way to create a data frame "like" another, but with more rows? What I'd like to do is this: if mydata is a data.frame like a b c 1 TRUE yes 2 FALSE no 3 TRUE yes I'd like to get mydata2 with the same column names and column types, but without the values and with more rows. All I could think of was to manually do

Hi Folks, I''m sure tons of people are gonna ruin a whole drawer of their best panties over this one. Rick Olson worked on the mongrel_upload_progress gem, documentation and examples and has almost everything you need to do progress tracked file uploads using just Mongrel to handle the upload. This means that Rails (or any other framework) isn''t blocked while the upload

Hi everyone, Just wanted to tell you a little story. We''ve been enthusiastic puppet users since about a year ago here at the Geographic Institute of the University of Zürich. But we won''t use the zpool type ever again. Its just not worth it. Here''s what happened: . one of our servers lost knowledge about one of its zfs pools . puppet didn''t find the pool

Hello all, to obtain a list of all objects in all search paths, I've found the following to work: > biglist <- sapply(1:length(search()), objects) This more obvious one, however, does not work: > biglist <- sapply(search(), objects) Error in pos.to.env(pos) : invalid argument Still, search() gives [1] ".GlobalEnv" "package:ctest" "Autoloads"

Hello, I'd like to propose an extension to the function summary.aov. In Splus (2000, I don't know about other versions), summary.aov allows a parameter ssType to be set to 1 or 3 (defaults to 1) to choose the type of Sums of Squares. I know I can get Type III SS in R with drop1(model), but including the functionality into summary.aov would, in my opinion, - yield a more usable table

How can I access a function created in one data directory in another? I have been sourcing the text file that contains the function each time I go to another data dir. This is cumbersome, and I suspect there is a way to make functions global. Thanks in advance, S. David White Dept of Speech and Hearing Science Ohio State University Columbus, Ohio

Currently (R-1.4.1 as well as R-devel, according to http://stat.ethz.ch/R-alpha/R-devel/library/base/html/par.html), the html version of help(par) shows [...] lab A numerical vector of the form c(x, y, len) which modifies the way that axes are annotated. The values of x and y give the (approximate) number of tickmarks on the x and y axes and len specifies the label size. The default

Hello, first, I'd like to congratulate the core team to the new R version 1.1. I think it's a great update, with glimpses into an even greater future (tcltk!). While playing around with the new functions (on Win 95), I found the following: As the documentation states, when I generate a plot and save it with recordPlot, I can regenerate it by printing the variable: > plot(1:10) >

Hi list, I have tried to reach Bradley (author of mongrel_cluster) by mail, but have not gotten a response. So I''ll try trough this channel: I have ''developed''[1] a small extension to mongrel_cluster that allows selective restart of any one listener in a configuration that contains more than one listener by using a command like mongrel_rails

Hello, is there a quick way of estimating Weibull parameters for some data points that are assumed to be Weibull-distributed? I guess I'm just too lazy to set up a Maximum-Likelihood estimation... ...but maybe there is a simpler way? Thanks for any hint (and yes, I've read help(Weibull) ;) Kaspar Pflugshaupt -- Kaspar Pflugshaupt Geobotanical Institute ETH Zurich, Switzerland

I frequently use hclust on a similarity matrix. In R only a distance matrix is allowed. Is there a simple reliable transformation of a similarity matrix that will result in a distance matrix making hclust work the same as S-Plus with a similarity matrix? Venables & Ripley 3rd edition implies that a simple reversal of values will suffice. Thanks -Frank -- Frank E Harrell Jr
