R help - Jan 2011 - Using plotLMER.fnc for lmer models with crossed random effects

Hi

I am attempting to use plotLMER.fnc
from the languageR library to plot
partial effects of models fited with lmer.


This appears to be straightforward for some of my models,
e.g:

 


>
mod<-lmer(NoBranches~PCA1+SP+(1|ProvCode)+(1|SoilZone),REML=FALSE,data=treedata1)  
> plotLMER.fnc(mod)
 

However, when a model contains crossed random effects, I
get an error message. e.g:

 
> mod<lmer(NoBranches~PCA1+SP+(1|ProvCode)+(1|SoilZone/ParcelleID),
REML=FALSE,data=treedata1)    
> plotLMER.fnc(mod)
Error in 1:(which(predictors =ranefnames[1]) - 1) : 

                argument of length 0

 

Any suggestions greatly appreciated.
