A general description is here.
‘callNextMethod()’ was broken when called from a method that augments the formal arguments of a primitive generic.
Coercion of an S4 object to a vector during sub-assignment into a vector failed to dispatch through the ‘as.vector()’ generic (often leading to a segfault).
‘match(x, t)’, ‘duplicated(x)’ and ‘unique(x)’ work as documented for complex numbers with ‘NA’s or ‘NaN’s, where all those containing ‘NA’ do match, whereas in the case of ‘NaN’'s both real and imaginary parts must match, compatibly with how ‘print()’ and ‘format()’ work for complex numbers.
