Dear R-help, Can anyone explain the meaning of the warning, Singular precision matrix in level -1, block 1 ? Or how to track down where it comes from? More precisely, using the nlme package, I'm issued with the warning itt2 <- lme(lrna~rx.nrti+lbrna, random=~1|patid, cor=corExp(form=~days|patid,nugget=T), weights=varPower( form=~lbrna),data=rna3) Warning messages: 1: Singular

Someone has reported a problem with predict.coxph that I can't seem to solve. The underlying issue is with model.frame.coxph; the same issue is also found in lm so I'll use that for the example. -------------------------- > test <- data.frame(y = 1:10 + runif(10), x=1:10) > myfun <- function(formula, nd) { fit <- lm(formula, data=nd, model=FALSE)

Dear List, I am doing some simulation in R and need basic help! I have a list of animal families for which i know the number of species in each family. I am working under the assumption that a species has a 7.48% chance of being at risk. I want to simulate the number of species expected to be at risk under a random binomial distribution with 10,000 randomizations. I am relatively knew to

Hi, I have this small problem with my servers managed by Puppet (i have a workaround so the problem is not so important): 1) These servers are installed with Red Hat Linux Enterprise and i use Puppet in client-server mode. 2) I''ve made a Puppet class called "yum" to install (by the RPM package provider) and configure YUM on my servers. I don''t use the YUM package

Dear List, I have a table i have read into R: Name Yes/No John 0 Frank 1 Ann 0 James 1 Alex 1 etc - 800 different times. What i want to do is shuffle yes/no and randomly re-assign them to the name. I have used sample() and permute(), however there is no way to do this 1000 times. Furthermore, i want to copy the data into a excel spreadsheet in the same order as the data was input so i can

Hi all, I just stumbled over a huge rails.log in /var/log/puppet on the puppetmaster. It is full of DB statments which seems to point to the fact that puppetmaster''s rails environment is set to development. No problem, I thought, set the system''s RAILS_ENV to production make it available to the master daemon and restart it. Unfortunately, this does not work. I searched
