Hi all, I wish to do build discrete choice model to analyse habitat selection of wolverines. This can be done with a 'tricked' stratified Cox proportional hazard model. For each individual animal each selected position, and possible alternative non-used available positions are combined into strata. This means that one stratum contains a set of 1 used position and several positions which

Dear R-users, I intend to do a spatial analysis on the genetic structuring within a population. For this I had thought to prepare a kernel density estimate map showing the spatial distribution of individuals, while incorporating the genetic distances among individuals. I have a dataset of locations of N unique individuals (XY-coordinates) and an NxN matrix with the genetic distances given as a

Hi, I am using lmer to analyze habitat selection in wolverines using the following model: (me.fit.of <- lmer(USED~1+STEP+ALT+ALT2+relM+relM:ALT+(1|ID)+(1|ID:TRKPT2),data=vdata, control=list(usePQL=TRUE),family=poisson,method="Laplace")) Here, the habitat selection is calaculated using a so-called discrete choice model where each used location has a certain number of alternatives

Hi all, I am using Match directive and internal-sftp to chroot sftp users into their directory. Connection and login works. I can change directories and put/get files. Also logging of the internal sftp-process works (created a /dev/log socket inside the chroot). As soon as I use the 'ls' command, nothing happens and the the process gets stuck. Listing files does work as soon as I remove

Hi, I change the dovecot.conf default_mail_env = mbox:/Mail/IMAP/%u/:INBOX=/var/mail/%u After I did the change, I restart dovecot with the hope that folder that I create will be stored in /Mail/IMAP/%u. Then I use Mozzila as my email client and change the IMAP server directory to ~nina/IMAP/ which is the link to /Mail/IMAP/nina/. But then I can not create folder anymore from Mozzila, or view

Dear all, The Norwegian Institute for Nature Research (NINA) seeks a post doc or Ph.D. candidate in mapping and valuation of ecosystem services from green infrastructure in Oslo. The candidate has preferably skills in Open Source GIS (OSGeo) and a M.Sc./Ph.D. in geomatics with an interest in urban ecosystem services, or a M.Sc./Ph.D. in nature management, landscape architecture, geography,

Hi, This may or may not be slightly off topic, but I'll stick my neck out... I want to launch an external application from R while retaining R as the active application window (with R console as the active R window). I'm using shell.exec() to sequentially open and evaluate the contents in all jpeg images in a specific folder, using the viewer specified by the file association (in my case

I am running the aov function to determine the linear relationship between individual genes and a number of covariates in a micro-array data set. My aov function is working, but I have not been able to write a code to save these results in a matrix. I am using the following code or a slight variation of this code: for(i in 1(length(m[1,])-20) {tmp<- aov(m[,i]~treat, data=m)

I am trying to upload into R 143 Affymetrix chips onto using R on the NIH Nimbus server. I can load 10 chips without a problem, however, when I try to load 143 I receive a error message: cannot create a vector of 523263 KB. I have expanded the memory of R as follows: R --min-vsize=10M --max-vsize=2500M --min-nsize=10M -max-nsize=50M (as specified in help in R). After running this command the

Dear R-users, another question concerning a persp()-plot: What does it depend on which line is labeled as an axis? Some plots I've done look fine, but in one plot, a different line is labeled. I can't find out why, as I just copied the code. Two small *.ps-grafics can be downloaded on http://www.math.uni-bremen.de/~nina/grafic.html to illustrate my problem. Thanks for your help in

Hi, I am extracting data from a table where the rows have different column lengths, and empty columns have NA in them. Whenever I extract a row with some empty columns, the resulting vector carries all the NAs. Is there a way to ignore the empty columns? Thanks, -Nina

hi vitamin. I now understand your suggestion is how to install, but..... I use UBUNTU 8.04 latest update and Wine 1.1.6 is installed. And so is the Polar ProTrainer 5 SW - from CD. (PTT 5) PTT 5 is working - so and so. It contains a calender and the picture-rendering i overlaping, but this is a minor concirn. My problem is that the buildt in uptateSW do not work, and there is alot of necesery

Dear R-users, I'm trying to recode a variable. After using cut(data.vector,breaks=my.breaks,labels=my.label) I need the data.vector to have the same values as the labels. To make it clear: x<-runif(10) y<-cut(x,breaks=c(0,0.3,0.7,0.9,1),labels=c(3,6,7,9)) as.numeric(y) returns something like a vector 1 3 3 2 2 1 4 2 3 4 . I need something like 3 7 7 6 6 3 7 9 6 7 9 for further use. I

Hi, I have a CSV file with various biological reactions. Subscripts, superscripts, and italics are encoded in carats, and I was wondering if R can actually recognize those and print actual superscripts, etc. Here's an example: <i>S</i>-adenosyl-L-methionine + rRNA = <i>S</i>-adenosyl-L-homocysteine + rRNA containing
