Check if a numeric matrix generated with make_adjacency fulfills the edgynode standard format

This function takes an adjacency matrix as input and checks if it is in a standard form (based on the options provided).

Usage

is_standard(adj, max_value = 1, no_negative = TRUE, no_self_loops = TRUE)

adj: an adjacency matrix converted from a raw input matrix via make_adjacency.
max_value: the maximum (positive) value that should exist in the matrix; default is 1; setting this to NULL or max(abs(adj)) leaves the values unchanged
no_negative: whether there should be negative values or just their absolute value (e.g. in the case of correlations); default is no_negative = TRUE.
no_self_loops: whether the values in the main diagonal of the adjacency matrix should be 0; default is no_negative = TRUE.
