Hi all,
I'm trying to fit models for data with three levels of nested random
effects: site/transect/plot. For example,
modelincrBS<-glmer(l.ru.ba.incr~shigo.av+pre.f.crwn.length+bark.thick.bh+Date+slope.pos.num+dens.T+dbh+leaf.area+can.pos.num+(1|site/transect/plot),
data=rws30.UL, family=gaussian, na.action=na.omit)
but I get the following error:
Error: length(f1) == length(f2) is not TRUE
In addition: Warning messages:
1: In plot:(transect:site) :
numerical expression has 92 elements: only the first used
2: In plot:(transect:site) :
numerical expression has 92 elements: only the first used
The formulation works for two nested effects (e.g. 1|site/transect)
I can get it to run in lme
modelincrBS<-lme(l.ru.ba.incr~shigo.av+pre.f.crwn.length+bark.thick.bh+Date+slope.pos.num+dens.T+dbh+leaf.area+can.pos.num,
data=rws30.UL, random=(~1| site/transect/plot),na.action=na.omit)
but I can't specify a distribution family in that package.
Any help much appreciated.
Ben Caldwell
