[R] drop.terms and [.terms ignores intercept

[Niels Richard Hansen]

Dear R-help list

The functions drop.terms and [.terms ignores if the intercept
has been explicitly removed. Is that a deliberate feature?

For instance,

drop.terms(terms(~a+b-1),1)
terms(~a+b-1)[2]

R version 2.12.0 Under development (unstable) (2010-09-13 r52905)

Best, Niels
