There are no known problems with 'RedHat compilers' and lme4.
You do need to have installed an up-to-date Matrix prior to lme4, and the

However, gcc 4.0.0 has many known problems, and

for(i in 1:100)
{

varname - paste(velocity,i,sep=)
assign(varname,read.csv(fn))

and you have a list of objects {velocity1, ..., velocity100} with

I run the code below the model summaries (AIC, BIC, loglik) differ between
the summary() and anova() commands. Can anyone clear up what's wrong?

I think you want to use text()

plot(x,y)
text(x,y, as.character(x), pos=4)

Dear Chris:
thanks for the prompt reply!
You are right, dist from pearson has negatives there, which I should
use cor+1 in my case (since negatively correlated genes should be
considered farthest). Thanks.
as to the ?cluster.stats, I double-checked it and I found I need to
restart my JGR, until

Thanks, that works well. Using layout also works. I suppose I
should have experimented with those earlier, but I somehow got it into
my head that split.screen was the modern and correct way to handle
this.
The lattice package is nice, but it isn't useful to me, since each

Hi, Andy:
Thanks very much. The 'strucchange' package (including its
vignette) provide useful food for thought. I haven't yet seen exactly
what I want, but I also haven't explored more than the vignette, and I
see other functions that may do what I want.
Thanks again.
Works on all platforms:
flist - list.files(path=file.path(somedir, somewhere),
pattern=[.]csv$)
csvlist - lapply(flist, read.csv, header=TRUE)
whateverList - lapply(csvlist, whatever)
