SUMMARY ------- Using package nlme, I am getting the following warning when I try to create a grouped data object using groupedData().
I believe that my logic is faulty. Warning message: In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else paste0(labels, : duplicated levels in factors are deprecated What am I doing wrong? How do I adjust?
