Accesses or replacees the column classes vector of a groupVec object.
Usage
groupVecClasses(object)
Arguments
object
the object to access.
Value
returns a vector of classes of object data.
Details
This function returns the classes slot of object.
It can also be used on the left side of an assignment to replace the 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 causes
the names and columns slots of object
to be extended or truncated to the new length.
