I just wanted to know whether the chances of getting help with this would
be greater if I posted this on the mixed models list, even though I would
be cross-posting.. ?

Dear R users,
I am trying to fit an lmer model with only random effects which is giving
me the following error:
Error : length(f1) == length(f2) is not TRUE
In addition: Warning messages:
1: In P1L55:family :
numerical expression has 390 elements: only the first used
2: In P1L55:family :
numerical expression has 390 elements: only the first used
I am trying to extract variance components for a phenotype 'peg.no',
using the variable 'family' and a marker column 'P1L55' (which is
categorical and has 2 levels- 0 and 1), as random effects. There are no
fixed effects.
The code I used is as follows:
vc<-read.table(...)
vcdf<-data.frame(vc)
colms<-(vc)[4:13] ##these are the markers
lapply(colms,factor)
try(fit<-lmer(peg.no~1 + (1|family/P1L55), na.action=na.include,
data=vcdf))
I thought that putting the data into a dataframe would help, along with
the na.exclude command, because there is a lot of missing data in patches
which I have replaced with NA's, but I don't know how to fix this error
at all.
Its a bit urgent, and any help is hugely appreciated.
The data files are at:
