mat_2scipy_sparse: conversion of an R matrix to a scipy sparse matrix

In mlampros/RGF: Regularized Greedy Forest

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.

Examples

try({
    if (reticulate::py_available() && reticulate::py_module_available("scipy")) {

        library(RGF)

        set.seed(1)

        x = matrix(runif(1000), nrow = 100, ncol = 10)

        res = mat_2scipy_sparse(x)

        print(dim(x))

        print(res$shape)
    }
}, silent=TRUE)
