## Sparse Matrix Coercion from and to those from package SparseM

### Description

Methods for coercion from and to sparse matrices from package SparseM are provided here, for ease of porting functionality to the Matrix package, and comparing functionality of the two packages. All these work via the usual `as(., "<class>")` coercion,

      as(from, Class)

### Methods

from = "matrix.csr", to = "dgRMatrix"

  ...

from = "matrix.csc", to = "dgCMatrix"

  ...

from = "matrix.coo", to = "dgTMatrix"

  ...

from = "dgRMatrix", to = "matrix.csr"

  ...

from = "dgCMatrix", to = "matrix.csc"

  ...

from = "dgTMatrix", to = "matrix.coo"

  ...

from = "sparseMatrix", to = "matrix.csr"

  ...

from = "matrix.csr", to = "dgCMatrix"

  ...

from = "matrix.coo", to = "dgCMatrix"

  ...

from = "matrix.csr", to = "Matrix"

  ...

from = "matrix.csc", to = "Matrix"

  ...

from = "matrix.coo", to = "Matrix"

  ...
