rbind2-method {MatrixExtra}

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.

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")
