Mike,
That's amazing, you nailed it, finally. Great!
Yes, I didn’t have all levels of stages that match all levels of Locations,
and because of this, I am getting such error messages. Thanks a lot indeed,
for educating and enlightening me, on these aspects.
I do have some other factors with
Mahen,
I think the issue is because you might not have all levels of Location matched
with all Levels of Stages. It appears you have 5 stages and 2 locations. For
the model that worked, you will notice 5 rows in your ANOVA table. In the one
that didn’t, it was attempting to create a table

Nevertheless, in this analysis the number of specimens (dependent shape
variable) is 147, obviously, with the equal number of observations for each
independent variables (here,
Mahen,
Can you be specific with the error statement? It might not me related to the
int.first use but more so how you set up your formula. If ind$Stages and
ind$Location are in the data frame, you are asking R to create a model matrix
from dat in an environment within another environment.
