That works, but I am still puzzled as to why lme(fixed = X.open ~ Dock, random=~Slip%in%Dock, data=my.data)
Does not work. It yields the error Error in getGroups.data.frame(dataMix, groups) : Invalid formula for groups Whereas were I to treat slip as a fixed factor aov(X.open ~ Dock + slipfactor%in%Dock, data=my.data) works just fine. Is there something fundamental that I am missing in the syntax?
