Dear R fans, I have got a difficult sounding problem. For fitting a linear model using continuous response and then for re-fitting the model after excluding every single variable, the following functions can be used. library(MASS) model = lm(perf ~ syct + mmin + mmax + cach + chmin + chmax, data = cpus) dropterm(model, test = "F") But I am not sure whether any similar functions is

Hello, Can anyone offer any insight on graphing classification dendrograms with the nodes marked? plot(tree()) produces a nice tree structure but there's no acccompanying text. Thanks, D S.

Hi All, I am trying to use a neural network for my work, but I am not sure about my approach to select a parsimonious model. In R with nnet, the IAC has not been defined for a feed-forward neural network with a single hidden layer. Is this because it does not make sens mathematically in this case? For example, is this pseudo code sensible? Thanks in advance for your help. I am sorry if this

Hi, I am using R on Debian Linux. I tried to install packages from inside R by calling function install.packages(), e.g., install.packages("tree"). The packages were installed successfully. However, I couldn't find the "src" subdirectory under the /usr/lib/R/library/tree directory,, which is supposed to contain the C, C++ and FORTRAIN source files, according to the

I want to remove files but only if they are owned by a certain user and group. Basically I have this: find /var/spool/greylist -mmin +363 -exec rm -f {} \; I want to make sure it only deletes files owned by mail. Basically no matter what weird characters are in the file names I want to make sure it does not delete anything outside of /var/spool/greylist. I can add 'sudo -u' to it but

Hello, Thought people might be interested in this. I want my voicemails emailed to a person and not stored on my asterisk server. However, I want them to have a sequential number. I found that if I set the option delete=1 in my voicemail.conf file for the mailbox, then the numbering would keep being restarted. I wrote this shell script to fool Asterisk into numbering my voicemails sequentially

Hi, I am trying to generate a group of graphics with an iteration. Some thing like this... x=1 y=1 max=10 myfiles <- paste("foo", x:max, ".png", sep="") while (x =< max) { png(file=myfiles, pointsize = 20, width = 600, height = 600, units = "px", bg="#eaedd5") plot(x,y) dev.off() x=x+1 y=y+1

I need to remove empty files out of a directory that are over 6 hours old so I created this script and put it in cron.hourly. #!/bin/sh cd /var/list sudo -u matt find /var/list -mmin +360 -empty -user matt -exec rm {} \; I want to run it as matt rather than root for just an added bit of safety. Problem is I get this. "sudo: sorry, you must have a tty to run sudo" Is there another

Dear all, I've been struggling for days now with a piece of code that I have posted here before, that has a really obscure bug. I think I may have isolated it, but I have no idea what it is.... It might also be a bug in R I guess, as it seems that one or several of list elements are not passed when a function is called, but quite rarely. I have been hacking rather wildly on the histogram

Hello, I am sorry if I am writing to a wrong list because honestly I do not know where to write but I would like to be able to set up sa-learn via cron to learn from spam folder of a particular email account (via IMAP). Can anyone share how to do it? Is dovecot involved in it? I am using: Exim 4.69 Dovecot 1.0.10 p5-Mail-SpamAssassin-3.2.1 Thanks a lot for helping. Zbigniew Szalbot

Dear all I have an sprintf inside a loop to track changes in variable's value. This sprintf statement works if I copy and paste it inside R sprintf('I did the the %d,%d \n',k,l) but when this is inside a loop I get no message. listcounter<-1 for (k in c(1:mmax)){ # for (l in c(1:nmax)){ lst[[listcounter]] <-fun(estimatedsr) listcounter<-listcounter+1

Hi, I've read as much as I can regarding the many problems people seem to have with -delete and none of the solutions seems to work for me. I have tried all combinations of using the trailing slash but it seems to have no effect. Does anyone know if -delete can work with -files-from? Here's the code: DIR="/mnt/backup/machine/oracle" FILES=".test_files.files"

Well after the 'issues' with Compaq C, I decided to attempt compile using GCC-3.4.3... To put it short, that didn't fair well either. Will L G.

Hello: I have a server set up a CentOS 5 server for a client to push files onto using FTP. I have a cron job to process the files and move them to another directory. Sometimes, the cron job executes while the client is still uploading a file (Some of them can be large) and I get a partial file. Is there a way to tell when a file has finished uploading? I am using the vsftpd daemon installed

Sorry for a bit longer delay than I anticipated, I was stuffed with the work. This is the next iteration of the patch adding some functionality to apcsmart driver, and relying on 'ignorelb' recently added. Follow up from previous thread: http://www.mail-archive.com/nut-upsdev at lists.alioth.debian.org/msg02331.html Main differences is that V3 is split into many small patches, so the

This patch introduces a handful of new options, I mentioned earlier in: http://www.mail-archive.com/nut-upsdev at lists.alioth.debian.org/msg02088.html See the large commit message in the follow-up for the details and rationale. I realize it's a bit larger diff - so if it's required I can split it into few smaller ones. Michal Soltys (1): APC smart driver update and new features.

Hi ! I have a server (Centos 5) that is using a pair of SAS drives to store the data.
