Hi syslinux experts, So, I have a pxe boot tree that looks something like this: /menu.cfg /linux /ubuntu /amd64 /meerkat (contains a mirror of the netboot ubuntu image) If I set the following in the appropriate stanza of my dhcpd.conf (for isc dhcpd v3), I can boot the ubuntu installer: filename "linux/ubuntu/amd64/meerkat/pxelinux.0"; next-server <tftp_server_ip>; I would

I am trying to add confidence (error) bars to lattice barcharts (and dotplots, and xyplots). I found this helpful message from Deepayan Sarkar and based teh code below on it: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/50299.html However, I can't get it to work with groups, as illustrated. I am sure I am missing something elementary, but I am unsure what. Using R 2.1.1 on various

Dear People, I just went back to an old piece of C code. On trying to compile it with the R math standalone C library I got the following error. Can anyone enlighten me what I am doing wrong, if anything? C file (rr-sa.c) follows. I'm on Debian sarge. I'm running R version 1.8.1. Gcc is version 3.3.1. Thanks in advance. Faheem.

I'm wondering if anyone can help me? I'm trying to run Secret of Monkey Island special edition in Steam on wine with Ubuntu Maverick Meerkat. I can install steam and use it to install the game (after it installs directx), apparently with no problems, but when I try to run the game, a window opens saying "Preparing to launch The Secret of Monkey Island: Special Edition".

Hi, I am new to R and I need to perform multiple chi-square tests. I manage to perform one at a time, but is there a specific command to do multiple tests? For example, I have a table that looks like this: Marker Treatment Genotype1 Genotype2 Genotype3 1 A 23 57 32 1 B 43 59 12 ... ... n A ## ## ## n

Hi All, I recently found gmane http://gmane.org/ It's a system to covert mail to news and back, with the nice property of keeping a searchable archive... Very convenient if you are subscribed to many lists and don't want to have your mail box cluttered. I use it to read several mailing lists already, but R is not available there. I wonder if the admins know about gmane and if they

Greg, I'm going to join issue with your here! Not that I'll go near advocating "Excel-style" graphics (abominable, and the Patrick Burns URL which you cite is remarkable in its restraint). Also, I'm aware that this is potential flame-war territory -- again, I want to avoid that too. However, this is the second time you have intervened on this theme (previously Mon 6

Hi, I'm trying to use a similarity matrix (triangular) as input for pam() or fanny() clustering algorithms. The problem is that this algorithms can only accept a dissimilarity matrix, normally generated by daisy(). However, daisy only accept 'data matrix or dataframe. Dissimilarities will be computed between the rows of x'. Is there any way to say to that your data are already a

Hello again, I have a Sola 305 (aka Powerware 3110) here connected via a serial INT-0051 cable which I am trying to get working with nut. The driver.list file indicates that nut supports the Sola 305 when connected via the INT-0025C cable using the genericups driver with upstype set to 7 but it does not mention the INT-0051. I was able to use the "Basic CheckUPS II" utility provided

Hi, I need to multiply all columns in a matrix so something like apply(x,2,sum), but using multiplication should do. I have tried apply(x,2,"*") I know this must be trivial, but I get: Error in FUN(newX[, i], ...) : invalid unary operator The help for apply states that unary operators must be quoted. I tried single quotes too, with the same results. Thanks, -Jose -- Jose

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm doing some basic operations on large sparse matrices, for example getting a row. it takes close to 30 seconds on a 3Ghz machine, and shots the memory usage up to the sky.

Hi All, If you use vim to edit R code, you may be interested in this. I have put together a personalized syntax file, some code templates, and a way to send code from Vim to R using autoHotKeys (windows). http://www.andrew.cmu.edu/user/jquesada/RvimSuite/instructions.html Actually, the little autoHotKeys can be useful even if you don't use vim just to send the example R code from the help

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have something strange here... I want to subset a large sparse matrix, with the subset being still in sparse form.

Hi, I'm trying to install R with atlas in ubuntu karmic 64. I do a lot of matrix operations so I need performance. Doing grep sse2 /proc/cpuinfo tells me tha my CPU supports SSE2. But I don't see libatlas3gf-sse2 in the package repositories. Also, there seem to be some gotchas on how to install atlas, even the vanilla one, as described here:

using latest stable version, 2.4.3 I've think i've got my configurations mostly working.
