In MatrixExtra: Extra Methods for Sparse Matrices

Concatenate sparse matrices/vectors by rows

Description

'rbind2' method for the sparse matrix and sparse vector classes from 'Matrix', taking the most efficient route for the concatenation according to the input types.

Arguments

x	First matrix to concatenate.
y	Second matrix to concatenate.

Value

A sparse matrix, usually in CSR format but some combinations might return COO or CSC.

Examples

library(Matrix)
library(MatrixExtra)
set.seed(1)
X <- rsparsematrix(3, 4, .3)
X <- as(X, "RsparseMatrix")
inherits(rbind2(X, X), "RsparseMatrix")
inherits(rbind(X, X, as.csc.matrix(X), X), "RsparseMatrix")
inherits(rbind2(as.coo.matrix(X), as.coo.matrix(X)), "TsparseMatrix")
inherits(rbind2(as.csc.matrix(X), as.csc.matrix(X)), "CsparseMatrix")
