as(object, Class, coerce=T)
object
is to be coerced to.
TRUE, a method for the
generic
coerce() is selected. If
FALSE, if an
is
relation exists for
object and
class, this will be used. An error
results if the coerce method or the
is
relation fails to exist, in the two cases.
This is the SV4 generic coercion function.
