Hi,
I am trying to analyze my data using a linear mixed effects model, using
the nlme package. The model I am using is:
>LW<-lme(fixed=r ~ t,random = ~ 1 | s, method=c("ML"), data=NPLW)
but, I am stumped with the error message:
Error in `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5", "6", :
attempt to set rownames on object with no dimensions
In addition: Warning message:
In Ops.factor(y[revOrder], Fitted) : - not meaningful for factors
Any help would be really appreciated!!
Thanks,
Megan
