mat_2scipy_sparse {RGF} | R Documentation |
conversion of an R matrix to a scipy sparse matrix
Description
conversion of an R matrix to a scipy sparse matrix
Usage
mat_2scipy_sparse(x, format = "sparse_row_matrix")
Arguments
x |
a data matrix |
format |
a character string. Either "sparse_row_matrix" or "sparse_column_matrix" |
Details
This function allows the user to convert an R matrix to a scipy sparse matrix. This is useful because the Regularized Greedy Forest algorithm accepts only python sparse matrices as input.

try({

res = mat_2scipy_sparse(x)
print(dim(x))
print(res$shape)
}
