groupVec Class Data Access
groupVec object.
groupVecClasses(object)
object data.
The function returns the
.Data.classes slot of
object. It can also
be used on the left side of an assignment to replace the
.Data.classes
slot with a new value. In that case, the data in the object columns
are coerced to the new classes. Also, replacement of the
classes with a vector of a different length will cause
the
.Data.names and
.Data slots of
object
to be extended or truncated to the new length.
