`sample_gnp_signed.Rd`

Generate random signed graphs according to the G(n,p) Erdos-Renyi model

`sample_gnp_signed(n, p, p_neg, directed = FALSE, loops = FALSE)`

- n
The number of vertices in the graph.

- p
The probability for drawing an edge between two arbitrary vertices.

- p_neg
The probability of a drawn edge to be a negative tie

- directed
logical, whether the graph will be directed. defaults to FALSE.

- loops
logical, whether to add loop edges, defaults to FALSE.
