corrgram (package corrgram): how to plot multiple correlograms in the same page?
...rgram. However, the function does not seem to use the base graphic system, as setting out the multiple figure layout with, e.g., par(mfrow=c(2, 2,)) does not work.
Does anybody know a workaround for this?
Many thanks in advance for any advice

Function nlme::lme in Ubuntu (but not Win or OS X): "Non-positive definite approximate variance-covariance"
...m unable to figure out the reason why I get such a difference in the
output: all the machines are running the latest version of R (3.0.1) and
nlme package (3.1-109) as of today (updated from the CRAN master site).
Many thanks in advance for any suggestions,
best

Repeated-measures anova with a within-subject covariate (or varying slopes random-effects?)
...Perhaps should lme() be used instead (and with which formula?)?
Many thanks in advance to anybody who'd be so kind to offer their
advice or tip on this. I have scoured the web and some textbooks for
a few days now, but to little avail.
very best

Julian dates
Hi all,
I have problems with years of dates using "chron" package.
I don't understand why R by this istruction:
> dates("01/02/29",out.format="d/m/year")
[1] 02/Jan/2029
> dates("01/02/30",out.format="d/m/year")
[1] 02/Jan/1930
reads "29" as 2029
and "30" as 1930. How could I change to read "00" to
2003 Nov 18

mixed model for Splus and R
Hi there,
I try to compare the mixed model package "lme" by Splus and R. I used the
dataset "Ovary" and the following code assuming AR(1) model for the error term:
lme(follicles ~ sin(2*pi*Time) + cos(2*pi*Time), data=Ovary, random =
pdDiag(~sin(2*pi*Time) ) , correlation=corAR1() )
But I got different results! And then I used a simpler model:
lme(follicles ~
