Incomplete-class: Class "Incomplete"

Description

a sparse matrix inheriting from class dgCMatrix with the NAs represented as zeros

Objects from the Class

Objects can be created by calls of the form new("Incomplete", ...). or by calling the function Incomplete

x:

Object of class "numeric" ~~

factors:

Object of class "list" ~~
