as.famset | R Documentation |
Create a set
of sets
from a binary
matrix where each row of the matrix is taken as one set.
as.famset(m, as.letters = TRUE)
m |
A binary matrix. |
as.letters |
logical, should the elements of the sets be letters or numbers? |
as.famset
takes a binary matrix and converts it to a family (i.e.
set
) of sets where each row of the matrix represents
one set and a "1" in row i and column j means that element j is contained
in set i.
If as.letters
is TRUE
the elements of the sets are letters,
otherwise numbers. However, if the matrix has colnames, these are taken
as names for the elements of the sets taking precedence over the
as.letters
parameter.
If the matrix contains the same row multiple times it is contained only once in the resulting family of sets.
