lme : Error in y[revOrder] - Fitted : non-conformable arrays
Greetings R-helpers,
I am attempting to fit an lme() while specifying a correlation
structure, but I'm getting into trouble long before I get to that point.
I am receiving the error:
Error in y[revOrder] - Fitted : non-conformable arrays
It doesn't seem to matter how simple or complex the model I specify is,
it always gives this same error message. This makes me suspect
something is

anova.gls from nlme on multiple arguments within a function fails
Dear All --
I am trying to use within a little table producing code an anova
comparison of two gls fitted objects, contained in a list of such
object, obtained using nlme function gls.
The anova procedure fails to locate the second of the objects.
The following code, borrowed from the help page of anova.gls,

NLME 3 (R version) again!
Hi,
Well after trying to fix the assign commands in version 3.1.7 of your nlme package
I still cannot get the plot functions to work. Basically I have no other packages installed (apart from those provided with R) so nlme is the first.
my R version info is;
platform sparc-sun-solaris2.7
arch sparc
os solaris2.7
system sparc, solaris2.7

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:

Problems with nlme (PR#471)
Dear R developers,
first of all let me join the chorus of congratulations for the release
of R 1.0.0. Well, done!
Unfortunately, I find it necessary to e-mail in a bug report regarding
the `nlme' package. On my office machine I experience the following
trouble:

segfault with correlation structures in nlme
Hi out there,
I am trying to fit a species accumulation curve (increase in number of
species known vs. sampling effort) for multiple regions and several
bootstrap samples. The bootstrap samples represent different
arrangements of the actual sample sequence.
I fitted a series of nlme-models and everything seems OK, but since the
observations are correlated I tried to include some correlation

Problem with nlme version 3.1-68
Dear All:
I updated my R program as well as associated packages yesterday. Currently
my R version is 2.2.1 running under WINXP SP-2.
When I tried to list (summary) an nlme object that I developed before, I got
the following error message:

Consulta gráfica
Hola,
Por favor, ¿podríais indicarme qué recursos (librerías o ideas) pueden resultar de utilidad para crear un gráfico del estilo del de la figura 3.8 del siguiente link?
http://www.tsc.uvigo.es/BIO/Bioing/ChrLDoc3.html#3.5
Actualmente estoy utilizando funciones muy básicas y la verdad es que no me encuentro muy satisfecha con el resultado.
Muchas gracias.

intervals in lme() and ill-defined models
There has been some recent discussion on this list about the value of using
intervals with lme() to check for whether a model is ill-defined. My
question is, what else can drive very large confidence intervals for the
variance components (or cause the error message "Error in

lme correlation structure error
Hi there fellow R-users,
I am trying to follow an example of modelling a serial correlation structure
in the textbook "Mixed Effects Model in S and Splus".
However, I am getting some very odd results. Here is what I am trying to
run:
library(nlme)
data(Ovary)
fm1<-lme(follicles~sin(2*pi*Time)+cos(2*pi*Time),data=Ovary,random=pdDiag(~s

Regresión lineal múltiple: modelo polinómico de grado 3 superpuesto a componentes cosenoidales
Hola:
Tengo un modelo de regresión lineal en el cual las componentes son cosenoidales, y lo construyo del siguiente modo:
modelo = "y ~ I(t) + I(t^2) + I(t^3) + x1[, 1] + x2[, 1]"
x1[, 1] = cos(2 * pi * t / periods[1])

No subject
about something else than the IP Trunk, he is talking
about outbound (which is related to using an
application to run an outside call, which is used
usually in campaign in contact centers and so on), I
think nthis case differs that placing a calls via IP
Trunk or even outside call but the caller who will do
it (and not the application).
Lastly, Mr. Amit helped me when he gave me a

tessellation from biological data in spatstat
Hi,
I'm new to this mailing list so apologies if this is too basic. I have
confocal images 512x512 from which I have extracted x,y positions of the
coordiates of labelled cells exported from ImageJ as a.csv file. I also
have images that define an underlying pattern in the tissue defined as
areas of different pixel values 0 or 255 (also 512x512) I've exported
these images as .txt

question about function "gls" in library "nlme"
Hi:
The gls function I used in my code is the following
fm<-gls(y~x,correlation=corARMA(p=2) )
My question is how to extact the AR(2) parameters from "fm".
The object "fm" is the following. How can I extract the correlation parameters
Phi1 and Phi2 from "fm"? These two parametrs is not in the "coef" componenet of "fm".

SwitchTower CVS support
I did an svn up this morning and discovered this whole new bundle of code!
Lookingn through it it looks cool, but there''s no CVS support for an SCM

at the code for subversion.rb and I thought it''d be possible to add a
