Error with corCompSymm and lme fit for repeated measures
Dear R Friends,
I need help with an error associated with corCompSymm in an lme fit.
I am using a mixed effects model to analyze a split-plot with
repeated measures and would like to fit with the compound symmetry
correlation structure. This problem doesn't occur when using
corAR1 or any of the other structures. I would greatly appreciate
help on how to solve this issue.

ordering in 'gnls' with 'corCompSymm' corStruct
Dear R-devel members,
While writing a new correlation structure similar to 'corCompSymm' and
intended to be used with 'gnls', I got puzzled with the 'Initialize' method.
Using 'Initialize' before 'gnls' may be regarded as a mean to set an
initial value for the corStruct parameter. However 'gnls' does not work
properly with a

nlme error message
Dear Friends,
I am seeking for any help on an error message in lme
functions. I use mixed model to analyze a data with
compound symmetric correlation structure. But I get an
error message: "Error in corMatrix.corCompSymm(object) :
NA/NaN/Inf in foreign function call (arg 1)". If I change
the correlation structure to corAR1, then no error. I have
no clue how to solve this problem.

corCompSymm in gamm()?
Hi,
I have confirmed temporal correlation problems in my data. Is there a
possibility to use corCompSymm for a gamm()?
I am an R-beginner.
I have very short time series. There are three years and within each year,
there are 10 weeks. he 10 weeks are the same every year and have not unique
values, I seem not to be able to use AR-1 (I assume that I have too little

R2.2.1 source compile problem in MacOS10.3
Dear R-list,
Realising the importance of updating the R base, I tried to compile the
source file of R2.2.1 in my machine, but failed.
According to "R for Mac OS X FAQ", i've got the basic dependencies
which are gcc 3.3 and g77 3.4.
./configure is fine

Error in load(dataFile, myEnv)
Dear all,
I just found that some of the packages are not able to load any more,
after I installed R2.0.1 in my Mac, it even affects my old R1.8
installs.
It gives me errors when I load packages that contains "myEnv" settings.
such as: RMySQL, DBI, Rggobi, etc. But others that does not require
"myENV" is all right, like tcltk that only calls the c functions.

repeated measures with gls
I am using the gls function of the nlme package to analyze data sets of
soil respiration which have the following design: 3 complete blocks x 5
sampling dates (time from fertilization) x 3 fertilization levels. The
fertilization dates are equal for all subjects (blocks) but not
periodical (-46, 10, 24, 53, 123 days from the event).
The code that I've been using is:

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:

slow load() in R2.6.0
I'm encountering excruciatingly slow load times for character vectors in
R 2.6.0-- up to 30sec for a 15K file that contains a no-attributes
character vector of length ~1e4 and object size ~0.5MB. In R 2.5.1,
repeated loads of the same set of files are near-instantaneous.
The problem is proving tricky to reproduce consistently from scratch, so

My own correlation structure with nlme
Dear all,
I am trying to define my own corStruct which is different from the
classical one available in nlme. The structure of this correlation is
given below.
I am wondering to know how to continue with this structure by using
specific functions (corMatrix, getCovariate, Initialize,...) in order to
get a structure like corAR1, corSymm which will be working for my data.
Thanks in advance.

Mean calculated from R1.9.1 different from R2.0.1
Hello,
I ran my simulations on the Unix verson of R1.9.1 and the Windows version
of R2.0.1 on XP. I kept getting different values for the mean of the same
column of the same matrix, and am perplexed. I would appreciate if anyone
could help explain the difference?
Here is a sample code:

z1v <- (z1v-mean(z1v))/sd(z1v)

installing the next version of R while in an older version
Hello -
I am a fairly new user of R. I currently have R1.7 installed. I tried to
install the KernSmooth package but a message tells me I need R1.8. Is there
a way to update to R1.8 while in R1.7 in the same manner that I can use
"update.packages", or do I have to install R1.8 in a separate directory and
re-install the many packages I have already installed in R1.7? Thanks in
