dse package problems
I am having problems with the package dse. I just installed R 2.2.1
and reinstalled all packages. I am running Windows XP Pro with all
updates.
Below there are two examples of error messages generated when trying
to execute some simple programs. The code was taken directly from the
package documentation.
Any help on this will be greatly appreciated.
Merry Christmas

Package DSE
Hi,
If I try to do this:
if(is.R()) data("eg1.DSE.data.diff", package="dse1")
model <- est.VARX.ls(eg1.DSE.data.diff)
(Page 14 - DSE Package Manual)
I obtain a Segment Violation.
I use R-1.3.0 and the last dse package version

lme4 groupedData is missing
help.search("groupedData") says that it's part of the lme4 package, but it
appears not to be there (details below). Is this because lme4 is new and
(perhaps) still under development?

groupedData Error Using outer=TRUE
I'm using groupedData from nlme. I set up a groupedData data.frame with
outer=~group1. When I try to plot with outer=TRUE, I get "subscript out
of bounds." This happens most of the time. When it works, I get
spaghetti-type plots for comparing groups. But I don't understand why it
doesn't usually work.

groupedData function not found
Hello,
I'm trying to use the groupedData function and R is giving me the message: Error: can not find function "groupedData"
The code is coming from a textbook so I think it should be correct:
pigs<-data.frame(cbind(pig.time,pig.id,pig.wt))
pig.growth<-groupedData(pig.wt~pig.time|pig.id,data=pigs)
I have added the package "nlme" and to confirm that it was installed

How to use groupedData() within a function?
Dear Group:
I have been trying to write an R function within which the function
groupedData() would be used.
The following is a sample program:

sid<-rep(1:6,times=2)
time<-c(1:12)
trt<-rep(letters[1:3],times=4)
tem<-data.frame(sid,time,trt)
test1.fun<- function(dat=dat)
{
groupedData(time ~ trt|sid, data=dat)
}

Repeated Measures, groupedData and lme
Hello
I am trying to fit a REML to some soil mineral data which has been
collected over the time period 1999 - 2004. I want to know if the 19
different treatments imposed, differ in terms of their soil mineral
content. A tree model of the data has shown differences between the
treatments can be attributed to the Magnesium, Potassium and organic
matter content of the soil, with Magnesium being the

How do I include a factor in a groupedData object? Meaning and use of inner and outer parameters

How do I include a factor in a groupedData object? Meaning and use of inner and outer parameters
Dear John
You are only allowed to have the primary covariate on the left hand side
of the vertical bar. Other covariates go in inner or outer.

groupedData
Dear all,
I tried to create a groupedData object, where the grouping factor
is not ordered.
Here ist the code:
library(nlme)
test<-groupedData(conc~Time|Subject,order.groups=F,data=as.data.frame(Theoph))
> getGroups(test)
Levels: 6 < 7 < 8 < 11 < 3 < 2 < 4 < 9 < 12 < 10 < 1 < 5
I still get an ordered factor. As always thanks for your help

wroung groupedData despite reading Bates and Pinheiro 3 times
Hi everyone. I am trying to add a formula to my data using the groupedData
function.
My experiment consists of randomized block design using fruits, vegetation
and time as factors. The idea is to see if fruits, vegetation and time
explain the abundance of mice. I am using tree density as a covariate.
So I tried to fit the following structure to my data.

plotting a groupedData object
Hello all,
I am plotting a groupedData object and the key at the top of the graph runs
off the page. I don't want to set key=F because it is useful (or would be if
I could see it).
Is it possible to explicitly cause the key to wrap? I have used this
function before with no trouble but now I have just 5 groups with rather
long descriptions (which I can't meaningfully shorten).

lme, groupedData, random intercept and slope
Windows Vista
R 2.10.1
Does the following use of groupedData and lme produce an analysis with both random intercept and slope, or only random slope?
zz<-groupedData(y~time | Subject,data=data.frame(data),
labels = list( x = "Time",
y = "y" ),
units = list( x = "(yr)", y = "(mm)")
)

scope of data in groupedData
I'm trying to write a function that has a dataframe as
an argument. Within the function, I call groupedData
to create a grouped-data object from the dataframe
argument. However, the groupedData function doesn't
seem to see the data. I'm guessing it's getting the
argument name rather than its value, but I'm not
positive.

plot groupedData in nlme
Hi,
Does anyone know how to make the color of the lines all black when
plotting groupedData with an outer factor:
For example,
library(nlme)
plot(Dialyzer, outer=~QB, key=F)
This generated colored curves in R.2.4.1. How to make all the curves black ?
(or how to alter the color (type) of lines for the nlme groupedData
plotting function in general?)
Thanks

Plotting groupedData objects
I am trying to create a plot similar to Figure 3.2 in Bates and Pinheiro.
I have repeated measurements on about 80 subjects from 2 treatment groups.
I would like to have the panels for the two treatment groups in separate
groups and within those groups have the panels ordered on maximum value
(as is the default).
I am ok with getting plots similar to Figs 3.1 and 3.2, but can't see how

Suppress legend in plotting groupedData
Dear All,
I would be grateful if you can tell how can I suppress the legend (automatically created) when I plot a groupedData.
suppose that I have data farme df_0 which contains the following columns: ID represents the clusters, t represents time of observation, Y: the variable of interest and X a binary covariate. Then:
df_1 <- groupedData(Y ~ t | ID)
