Dear Madame or Sir, in my current project, I have so far used a lot of very different plots. I am now trying to gain informatin with the help of parallel coordinate plots. Therefore, I use the function "parcoord" of the MASS package. What I would like to do, is to color let's say the points according to the first half of rows of a specific matrix/dataframe in a color different from

Dear R users, just a quick question: Is there a reliable and good graph library for R, eg. with shortest path algorithms on adjacency matrixes? I already found a graph package as part of "Bioconductor". Are there more? If anyone knows and would tell me, I appreciate very much! Cheers, Andre -- Dipl.-Inform.

Hello there everybody! Terrific... a mailing-list for compiz with David on board! Ok, I started off with writing some functions using cairo to draw me the needed elements for drop-shadows (atm stand-alone to focus on the proper generation of the shadow-parts) and currently still fiddle with the tweakable parameters. Right now I have... shadow-radius (e.g. 20 pixels) 2D-offset vector (e.g. 10

It seems that the standardized deviance residulas, that one gets on plots of a glm.object x with plot(x) are calculated as r <- residuals(x) s <- sqrt(deviance(x)/df.residual(x)) w <- weights(x) hii <- lm.influence(x)$hat r.w <- if (is.null(w)) r else (sqrt(w) * r) rs <- r.w/(s * sqrt(1 - hii)) This implies that, for example, for binomial B(ni,pi) data the devaince residials

Hallo Tk experts, the Tcl/Tk package allows to define very nice widgets for starting R functions, for printing results and for interactive parameter input. tkdensity.R and tkttest.R demonstrate this and both demos explain how some of the tk functions can be used. For constructing new widgets I would like to see further examples showing Tcl/Tk package in action. Therefore my question: Is there a

Hi, we've upgraded recently from samba 3.0.23 to 3.0.25b. Since then, we've getting these error messages from winbindd: Jul 17 12:00:23 cvk027 winbindd[20772]: [2007/07/17 12:00:23, 0] lib/util_str.c:safe_strcpy_fn(659) The volume of these messages is very high, many times together with unreadable character garbage. Is there any way to correct or suppress these messages? Our

Hi all I want to move mails from folder test-ein to another folder test-aus with the new "doveadm move" command in dovecot 2.0.12. When I try the following I get a "Segmentation Fault" after the mail was copied to the new folder: # doveadm -v -f flow search -u g033 mailbox test-ein all 56779e33a911b84db22900005451a966 1 # doveadm -v -f flow search -u g033 mailbox

Running dovecot 1.2.9 on a Ubuntu 10.04.1 LTS virtual machine. Postfix receives messages and hands them over to deliver for local storage. Today two mails came in that could not be found allthough they got delivered. What catches my eye is the "?" in the msgid: Jan 5 21:10:47 mail dovecot: deliver(consulting): msgid=? <14847_1294258245_ZZh0g1h9eLfxL.00_fc2fe6e910f03.4d24de54 at

Hi! I am using R 1.8.1 and the svm of the e1071 package for classification. The problem is that I have unbalanced classes e.g. the first one is much bigger than the second one and therfore the svm is biased to the first class. If I manually adjust the class size the bias disappears. The question is then how to include this unequal class distribution to the svm (e.g. via wheights or costs)?

Hi, I've encountered a strange problem while using FreeBSD 6.0 for our local mirror (mirror.math.uni-bielefeld.de) and thus is providing access via ftp, http, rsync and cvsup (all local and remote). The system crashes periodically with a kernel panic (panic: sbdrop). The uptimes between two crashes are going from a few hours to a few weeks. The system is a i386, Intel Pentium 4 based with

Hello! We are a group of three students at Bielefeld University currently working on a statistical projects about neural networks. Within the framework of this project we are supposed to use the nnet-function in R and explain how it works. Since anyone of us has much experience in using R we hoped to find some information on your homepage. Unfortunatelly, we haven't been very successfull so

Hallo, I use dovecot 2.1.7 with mdbox format and I specified a separate location for mailbox index files with mail_location = mdbox:/dovecot/storage%h:INDEX=/dovecot/index%h With this setting I get for every mailbox a directory under both filesystems /dovecot/index and /dovecot/storage, e.g. for the inbox it looks like that: # ls -lR /dovecot/index/home/hrz/myuser/mailboxes/INBOX

Hi! I am using the fft() function the base package to transform some 1d signal. If I use this standar fucntion I get a very huge first fourier coeficient. I think this dues to the handling of the borders of the signal. Usually in fft especially in image processing the signal is simulated to be continuous by adding the signal several times periodically. My question is, is there some function

Hello, can dsync convert from compressed mbox to compressed mdbox format? When I use compressed mbox files, either with gzip or with bzip2, I can read the mails as usual, but I find the following errors in dovecots log file: imap(userxy): Error: nfs_flush_fcntl: fcntl(/home/hrz/userxy/Mail/mymbox.gz, F_RDLCK) failed: Bad file number imap(userxy): Error: nfs_flush_fcntl:

Hello, when trying to set up a migration scenario from my old mailbox-servers to my new dovecot-cluster, I get a coredump from dovecot/lmtp when proxying mail-delivery to more than one recipient on the old mailbox-server. My setup: 3 director-hosts (Debian stretch) are proxying to a pair of replicator-hosts and during migration also to the old mailbox-server. For migration the not-migrated

Within a loop I tried to draw some things in dependency on the position of the mouse. This works fine with R-1.5.1 but R-1.6.1 requires to include some delay by Sys.sleep(delay) with delay>=0.015. For smaller values (e.g. 0.0001) the top level tcltk-window does not appear and so I am not able to control the elements to be plotted using the tcltk-widget. Question1: How can I force

Hi! I have a problem using the legend command. I typed as follows: plot(foo bar...) legend(0.6,10, c("True Positiv", "False Positive", "False Negative","True Negative"), col = c("black",2,3,4),lty=c(1,1,1,1),pch=c(0,0,0,0), merge = TRUE, bg='gray90') The plot and its legend is displayed ok.
