lme ->Error in getGroups.data.frame(dataMix, groups)
The basic idea is to create a linear model in R such that
FinH is explained by SoilNkh, dDDSP, dDDSP2, Provenance, Site, Genotype and Block, where SoilNkh, dDDSP and dDDSP2 are continuous covariates, Provenance, Site, Genotype and Block are factors, Site and Provenance are fixed and Genotype and Block are random. Also, Genotype is nested within Provenance and Block within Site.
Since the order the variables go in is of importance, it should be a Anova type-I with the parameters in following order:
FinH~SoilNkh,Site,dDDSP,dDDSP2,Provenance,Site:Provenance,Provenance/Genotype,Site/Block
For the fixed part I am oké with either:
test31 <-lm(FinH~SoilNkh + Site + dDDSP + dDDSP2 + Provenance + Site:Provenance ,data=d1)
test32 <-aov(FinH~SoilNkh + Site + dDDSP + dDDSP2 + Provenance + Site:Provenance ,data=d1
When trying to specify the random-part, taking the above text as starting point, trouble starts :)
I feel it should be of the form:
test64 <- lme(FinH~SoilNkh + Site + dDDSP + dDDSP2 + Provenance + Site:Provenance,
random = ~1|Provenance/Genotype + ~1|Site/Block,data=d1)
but I can't avoid the error
"Error in getGroups.data.frame(dataMix, groups) :
invalid formula for groups"
I am lost for clues, really, so any advice would be great! If any data should be supplied, I'd be happy to provide of course, but can't (yet) figure out how...
Thanks in advance for your time.
