I have tried substituting pol(Tr,1) for lin(Tr) in a repeated analysis
setting e.g. the rat data p122 but get error messages "...insufficient
points for pol(Tr,1).." when data is in multivaraite format or
"..structure/factor mismatch.." for univariate data.
How do I rewrite
!r units lin(Tr).units
using pol(Tr,1) ?
Thanks
