Read partitions from a binary file — enum_read

Read the binary file produced by enum_partitions() or enum_partitions_graph() when called with the file argument.

Usage

enum_read_partitions(file, skip = 0L, n = NULL)

Arguments

file: Character. Path to the binary file.
skip: Integer. Number of partitions to skip before reading. Defaults to 0.
n: Integer or NULL. Number of partitions to read. If NULL (default), reads all remaining partitions.

Value

An integer matrix with one row per cell/vertex and one column per partition read. Cell values are integers from 1 to the number of parts indicating part membership.

Examples

tmp <- tempfile()
enum_partitions(3, 3, num_parts = 3, min_size = 3, max_size = 3, file = tmp)
