Hi,
I am trying to analyze my data using a linear mixed effects model, using
the nlme package. The model I am using is:
>LW<-lme(fixed=r ~ t,random = ~ 1 | s, method=c("ML"), data=NPLW)
but, I am stumped with the error message:
Error in `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5"
Hi,
Another student here got the problem figured out!
R was calling the variable "r" a factor, not a number, and then it
couldn't fit an lme to a factor response variable
Thank you!

Volker,
You're welcome to take look at my site:

It's primarily for multivariate analysis in community ecology, bit does
also have some stuff on GLMs and GAMS in an ecological context. You
might also visit with Hank Stevens at Miami as he's just next d
Hi all,
I'll be teaching a 400/600 level bio/ecostatistics class using R this
fall (using "Introductory Statistics with R" as text book). I was
wondering if anyone here had any teaching material (lecture slides,
exercises, homework, projects, code for teaching etc) that they would
like to sha
