I have two specific questions regarding the output of lda function in MASS. #Question1: #========= n: sample size, p: number of variables Some articles in the literature say that LDA is singular for p > n-1. However, my experimentation with lda (default arguments) for two class problems shows collinearity for p > n-2. Does anyone know why this is the case? Does lda (MASS) use a different

Hi, I'd like to be able to log file transfers to/from an SSH server (both through scp and sftp-server). Perhaps I'm not looking in the right places, but I don't see a way of doing this in the current code. The "scponly" shell goes some (small) way towards doing this, however, it logs patterns rather than filenames in scp transfers. I have even less success with sftp. If

How can I get rsync to write a log record (like --log-format does for data transfer) when no content needs to be transferred but attributes (owner, group, mode, ...) are changed? -- Dave Mielke | 2213 Fox Crescent | I believe that the Bible is the Phone: 1-613-726-0014 | Ottawa, Ontario | Word of God.

When using --backup, the sequence (as monitored by strace) is: rename("/path/to/<file>", "<backup-dir>/<file><backup-suffix>") rename("/path/to/.<file>.xxxxxx", "/path/to/<file>") This, of course, leaves a momentary window wherein <file> can't be found. Might it be possible to replace the first rename()

Firstly can I ask when the documentation site will be online again? I'm struggling here without it. Further to my recent post I have tried to simplify things a little. I have used a VoiceXML app to simple call an asterisk extension. EG: <form id="transfer"> <block> <call name="xfer" dest="sip:101 at 10.0.4.147:5060"/>

Dear list, I am trying to use the 'mvrnorm' function from the MASS package for simulating multivariate Gaussian data with given covariance matrix. The diagonal elements of my covariance matrix should be the same, i.e., all variables have the same marginal variance. Also all correlations between all pair of variables should be identical, but could be any value in [-1,1]. The problem I am

Dear list,   I am looking for an R-only implementation of a Nelder-Mead process that can find local maxima of a spatially distributed variable, e.g. height, on a spatial grid, and outputs the coordinates of the new point during each evaluation. I have found two previous threads about this topic, and was wondering if something similar has been implemented since those messages were posted.   Thank

Dear list, Most high performance computing clusters/grid engines have some restrictions on how long a job can be run in batch mode. The cluster I am using has maximum of 48 hours limit, but my job would take far more than that. I know that it is possible to checkpoint jobs without modifying the code if some specialized software (e.g., BLCR ) is installed on the grid engine. However, I am

I''m trying to create a sequence with no gaps in my db (contrived example, but should work out the same as my real one), and believe db-managed transactions are the way to go about this. It''s my first real ''go'' at transactions, so I may be mistaken about how things really work. Anyway.. Consider this example code: Class Invoice < ActiveRecord::Base def

Dear r-help, Sleep-deprivation from having 2 youngsters under 2 around the house is fuzzing my brain, so please be gentle if the answer to this query is obvious! In the example below, I'm trying to use grid.rect to add grey rectangles to the panels of a lattice plot to indicate which months spawning occurred of a (very cute) native Tasmanian fish. The fish in the two lakes spawned at

Dear R users, I have a rather knotty analysis problem and I was hoping that someone on this list would be able to help. I was advised to try this list by a colleague who uses R but it is a statistical inquiry not about how to use R. In brief I have a 3x2 anova, 2 tasks under 3 conditions, within subjects. I also took a variety of personality measures that might influence the results under the

Dear list, ? I am trying to program semi-random movement within a circle, with no particles leaving the circle. I would like them to bounce back when they come to close to the wall, but?I don't seem to be able to get this right. ?Would somebody?be able to?give me a hint ? This is my code so far, the particle starts at some point and moves towards the wall, but I don't get the

Hi I'm using a function (arrayview from the maanova package) that produces 12 plots, all in separate windows. How can I get each one to print to a jpeg file as the plots are produced? Alternatively, is it possible to get dev.print (jpeg.....) to print all open graphics devices to separate windows? Thanks in advance, Nat Street -- Nathaniel Street University of Southampton

Hi I have a column of concatenated information stored in an RG object in the limma package and I need to split this information and then paste the first two pieces of data in each case back into two columns of the RG object. This is how I am currently doing this gene.info.split<-strsplit(RG$genes$Name,",",fixed=TRUE) for (h in 1: length(gene.info.split)){

I need to specify error terms properly in a mixed-effects anova model. I know you can add error terms in aov using Error and can specify random factors in lme but I am not sure how these get treated. When making the calculations for fixed and random factors, are the correct error terms used and how can you get aov or lme to use different error terms for fixed and random effects? I'm

Hello! First, sorry for my English... I'm a newbie with Dovecot and I have some questions, I'm testing Dovecot 1.1.11 in a virtual machine. I wish in the future, migrate this to a real server. Ok, but i need this: 1) A group of users can use IMAP or POP3. 2) The others, only can use POP3. But, this users can use IMAP only with a webmail (the webmail is in the same server that

Hi: Two scripts (mkbd.fails and mkbd.works) are attached to this message. The only difference between them is in how syslinux.cfg (on a RedHat boot image) is replaced. mkbd.fails: syslinux.cfg is replaced via "mv -f". vmlinuz can't be found. mkbd.works: syslinux.cfg is replaced via "cp". vmlinuz is found. The only difference I can see between these two methods is that

I have a repeated error in the asterisk console. Incoming call: Got SIP response 400 "Bad Request" back from 10.0.2.136 It is repeated every few seconds and never stops until I restart Asterisk. It starts after I make a call to a certain extension, 202 which transfers the call to another extension all phones then hang up. The SIP trace looks like:
