Simple example of variables decorrelation using the Cholesky decomposition
Dear all, I made a simple test of the Cholesky decomposition in the package 'Matrix', by considering 2 variables 100% correlated. http://blogs.sas.com/content/iml/2012/02/08/use-the-cholesky-transformation-to-correlate-and-uncorrelate-variables/ The full code is below and can be simply copy&paste in the R prompt. After uncorrelation I still have a correlation of +-100%...

retrieve most abundant species by sample unit
Hi R-users: [R 2.2 on OSX 10.4.3] I have a (sparse) vegetation data frame with 500 rows (sampling units) and 177 columns (plant species) where the data represent % cover. I need to summarize the cover data by returning the names of the most dominant and the second most dominant species per plot. I reduced the data frame to omit cover below 5%; this is what it looks like stacked. I have

Simple GLS regression with CAPER
Dear R experts, I hope this is the right list for my question. As a newcomer in R, I am testing the R CAPER package, applying a simple regression on a phylogeny tree with three binary traits: (t1, t2, t3). My goal is to test the sensitivity to a correlation between t1 and t3. But if a correlation of 100% is considered (i.e. t3 = t1). The pgls method of CAPER seems to crash: You can find there

Mainpine OCTO+ and CentOS v4
I've been having a problem with getting a Mainpine OCTO+ working on CentOS Version 4. I know at some point I'll have to recompile the kernel in order to access all 8 ports but something is still not right. Wvdialconf almost every will id all of the ports. All too often it can fine the modem on at least half the ports on the board. I'm starting to hear that something is not right on V4

reference-style/shortcut syntax
I also agree that single bracket reference-style syntax is not prudent. As Jacob suggested, it creates ambiguity for the reader (Is it an edit or a link?). It also creates a new problem of potential conflict, however rare that may be. It seems reasonable to prefix a marker colon (possibly followed by whitespace): [:ref link] or [: ref link] And perhaps the same for attributes: {:att ref} or {:

as.integer(TRUE)
The fact that as.integer(TRUE) is 1 (and that for FALSE, it gives zero) is a really nice feature, eg when constructing piecewise functions (for example, as in -x*(x<0)+x*(x>=0)) and for many other things. Since I haven't found a reference about this, I just wanted to ask whether this is officialy part of the language or just a side effect (ie I want to know whether it is here to stay

Braindead Autoreply filters... WAS Re: samba Digest, Vol 102, Issue 8
It would be nice if one of the list moms would immediately unsubscribe AND PERMANENTLY BAN idiots who use braindead autoreply filters. This should be official list policy for ALL email lists...

MD5/Checksums for debug files?
Being new at distro SOPs, I don't know if this is an unusual thought. With a kernel debug package (or any such debug package) would it be prudent in todays world to have a checksum or signature process to assure the downloaded file is untampered with and complete? What prompts this is I just downloaded the kernel packages that Johnny put up. I had not realized they were so large and thought

Question about host certificates
Hi, I'm experimenting with host certificates in 5.4p1 and seem to have hit a usability issue. I've generated a host certificate, added the HostCertificate option to the sshd_config and restarted sshd. I've replaced the system's ssh_known_hosts file with one that has a single entry of the form: @cert-authority *.example.domain ssh-rsa ... This works provided that I use the

Building a new 2.6 kernel

dgamma density values in extreme point
Dear R-Devel group, My name is Alexey, a data scientist from Moscow, currently working for Align Technology Inc. We have recently had a discussion of the results that the dgamma function (stats) returns for an extreme point (x == 0). <dgamma(0,1,1,log = FALSE) [1] 1 and <dgamma(0,0.5,1,log = FALSE) [1] Inf Density appears to be defined in point zero for the distribution with the
