NLME: Limitations of using identify to interact with scatterplots?
...regarding the use of identify to interact with
points on a scatterplot. My question is essentially: can identify be used
when one is plotting model objects to generate diagnostic plots?
Specifically I am using NLME.
For example, I am plotting the fitted values on the x axis vs a variable
called log2game with the following code:
plot(D2C29.nlme, log2game ~ fitted(.), abline=c(0,1))
and then I have tried to use identify as follows:
identify(D2C29.nlme$fitted[,2],Data2$log2game,row.names(Data2))
(if I leave out the [,2] on the fitted attributes then I am told that x and
y are not the same lengt...

NLME: Problem with plotting ranef vs a factor
...t; and the "levels" command that it is a factor. Yet despite this the plot command is not recognising it as a factor.
Here is more information about my problem:
I am reading in the data by:
Data<-read.csv("Data1_93_2.csv",header=T)
attach(Data)
Data1_93<-transform(Data,log2game=log2(gamedens+1))
pcat<-as.factor(pcat)
Data1_93<-groupedData(log2game ~ day | subjectno, data=Data1_93)
detach(Data)
Here is the code to check that the covariate called pcat is indeed a factor:
> levels(pcat)
[1] "1" "2" "3"
> is.factor(pcat)
[1] TRUE...
