sparse_subset: sparse_subset

In mskilab/skitools: Various mskilab R utilties

sparse_subset

Description

given k1 x n matrix A and k2 x n matrix B returns k1 x k2 matrix C whose entries ij = 1 if the set of nonzero components of row i of A is a (+/- strict) subset of the nonzero components of row j of B

given k1 x n matrix A and k2 x n matrix B returns k1 x k2 matrix C whose entries ij = 1 if the set of nonzero components of row i of A is a (+/- strict) subset of the nonzero components of row j of B

Usage

sparse_subset(A, B, strict = FALSE, chunksize = 100, quiet = FALSE)

sparse_subset(A, B, strict = FALSE, chunksize = 100, quiet = FALSE)

Arguments

A	k1 x n matrix
B	k2 x n matrix
strict	logical flag whether to return strict subset (=FALSE)
chunksize	integer size of rows to process from each matrix at a single iteration (=100)
quiet	logical flag (=FALSE)

Value

k1 x k2 matrix C whose entries ij = 1 if the set of nonzero components of row i of A is a (+/- strict) subset of the nonzero components of row j of B
