Why are coefficient estimates using ML and REML are different in lme?
Hi, All,
My data collection is from 4 regions (a, b, c, d). Within each region, it has 2 or 3 units. Within each unit, it has measurement from about 25 sample site. I was trying to use lme function to discribe relationship between y and a few covariates. Both y and covariates were measured at the sample site level. My question is when I use exactlly the same model but choose different estimation

Hi,
this is not a new doubt, but is a doubt that I cant find a good response.
Look this output:

Kaplan-Meier function from survfit
Hi All,
Please pardon me if I am missing something obvious here. How do I get
the Kaplan-Meier estimate function that is created by survfit and
plotted by the code.
fit <- survfit(Surv(time, status) , data=aml)
plot(fit)
That is, I need a function that will give me the survival estimate at
a given time: \hat{S}(t).
Thanks in advance.

metafor - multivariate analysis
Dear Metafor users, I'm conducting a metaanalysis of prevalence of a particular behaviour based on someone elses' code. I've been labouring under the impression that this:
summary(rma.1<-rma(yi,vi,mods=cbind(approxmeanage,interviewmethodcode),data=mal,method="DL",knha=F,weighted=F,intercept=T))
is doing the multivariate analysis that i want, but have read that

Matrix eigenvectors in R and MatLab
Dear R-listers
Is there anyone who knows why I get different eigenvectors when I run
MatLab and R? I run both programs in Windows Me. Can I make R to produce
the same vectors as MatLab?

[PATCH v10 0/5] make balloon pages movable by compaction
Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

A question about the ff package
Hi,
I am using version 2.1-1 of the ff package.
I have a data set with 80 million rows and I need to create a new ffdf
object, subseting by values in one of the original ffdf's columns. Here is
my code:
bigData <- read.table.ffdf(file="/data/demodata/data/smallData.txt",
next.rows=1e5, head=TRUE, sep="|")
dim(bigData)
N <- nrow(bigData);N
select <- ff(
