imagine when you have complicated matrix algebra computation using R,
you cannot prevent some middle-terms become quadratic and absorbs into one
scalar, right?
if R cannot intelligently determine this, and you have to manually add
drop everywhere,
do you think it is reasonable?

For descriptive purposes I would like to add attributes to objects. These

I noted that some attributes like levels and class of a factor exist also
