Sparse: To store in i,j,x sparse matrix format

In INLAtools: Functionalities for the 'INLA' Package

To store in i,j,x sparse matrix format

Description

To store in i,j,x sparse matrix format

Usage

Sparse(A, unique = TRUE, na.rm = FALSE, zeros.rm = FALSE)

Arguments

A	matrix or Matrix
unique	logical (default is TRUE) to ensure that the internal representation is unique and there are no duplicated entries. (Do not change this unless you know what you are doing.)
na.rm	logical (default is FALSE) indicating if it is to replace ‘NA’'s in the matrix with zeros.
zeros.rm	logical (default is FALSE) indicating if it is to remove zeros in the matrix. Applied after na.rm.

Note

This is based in INLA::inla.as.sparse(), but allow all combinations of 'na.rm' and 'zeros.rm'.
