the empty ones.

lmer: Estimated variance-covariance is singular, false convergence
...uot;Cracks" and tried to exclude
some of them in different ways (as all transects without vegetation
cover), but this did not help. The current version deals with all
transects wich have at least two plots with crevices.
The correlation Intercept/Cracks ist -1.000 for both models.
I attachet a symmary of the used data.frame, a randomly selected subset
and the summarys of cracks.lmer and cracks.lmer1 in a *.txt file
(modified with kate). Some xyplots are attached as *.png. (The error
message on the plots means "Error using packet 5, NA/NaN/Inf in externem
Funktionsaufruf", excluding the...

Nestad ANOVA with random Factors
...with three factors: Day, Area
and Plot and the dependent variable is density. The factors Day and Area are
fixed while Plot is random, factor Area is nested in factor Day, and factor
Plot is nested in Area.
I can do it using aov by:
mod1<-aov(density~ day + day%in%area + day%in%area%in%plot)
symmary(mod1)
Getting this result:
