How to conduct a MANCOVA

问题

I am trying to perform a mancova in R. However, I have tried the jmv package:

x<-cbind('total.c','total.p') #dependent
y<-cbind('Treatment','Sex', 'Species', 'Location') #independent
mancova(intake, deps=x,factors=y, covs=c("Ghopper.Start..g."))

which gives me the following error:

Error: Table$setRow(): value 'stat[pillai]' is not atomic

When I remove one of the independent variables, the function works with no problems. So I am suspecting its a memory limitation,, but what actually is going wrong here?
