`Hi guys,
I´m quite new to R, but I still try my hand on a discontinuous growth modeling using nlme. To test, if it makes sense to enter a random slope into the model, I´ve used the exactRLRT function, unfortunatly I´ve got the following Error: Error in matrix(unlist(value), nrow = nrow(data), dimnames = list(row.names(data), : length of 'dimnames' [2] not equal to array extent
I cannot find any reasons, since the three compared models´ve worked well and all consist of a "List of 18" [from environment].
The ICC (1) with multilevel level package was significant.
I do not know, why it fails ...
I´m thankfull for any kind of help
AC`
