GAMatrixInt* GA_matrix_from_R_int

(

SEXP

robj

)

Create matrix from R object (int).

Create a matrix of integers from an R object. The new matrix will be referenced and should be destroyed by using GA_matrix_destroy_int() when it is not needed anymore.

Parameters:

robj

R object.

Returns:

Pointer to a matrix, or 0 if an error occurs.

GA_matrix_destroy_int

GAMatrixReal* GA_matrix_from_R_real

(

SEXP

robj

)

Create matrix from R object (real).

Create a matrix of real numbers from an R object. The new matrix will be referenced and should be destroyed by using GA_matrix_destroy_real() when it is not needed anymore.

Parameters:

robj

R object.

Returns:

Pointer to a matrix, or 0 if an error occurs.

Parameters:

matrix

Matrix.

Returns:

R object.

SEXP GA_matrix_to_R_real

(

GAMatrixReal *

matrix

)

Create R object from matrix (real).
