Create a Hypergraph From an Incidence Matrix

Description

Create a Hypergraph From an Incidence Matrix

Usage

hype_from_inc_mat(inc_mat, directed = FALSE, real_coef = FALSE)

Arguments

inc_mat	An incidence matrix or, for an oriented hypergraph, a list of two incidence matrices.
directed	A logical value representing whether the hypergraph should be directed.
real_coef	A logical value representing whether the hypergraph should have real coefficients associating vertices to hyperedges.

Value

A hypergraph object with the given incidence structure.

Examples

i1 <- matrix(
  c(1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 0, 1, 0, 1, 0),
  nrow = 5,
  ncol = 3,
  dimnames = list(
    paste0("v", 1:5),
    paste0("h", 1:3)
  )
)
hype1 <- hype_from_inc_mat(i1)

i2 <- list(
  matrix(
    c(1, 1, 0, 0, 1, 0, 0, 1, 0, 1, 1, 0),
    nrow = 4,
    ncol = 3,
    dimnames = list(
      paste0("v", 1:4),
      paste0("h", 1:3)
    )
  ),
  matrix(
    c(0, 0, 1, 1, 1, 1, 0, 0, 1, 0, 1, 0),
    nrow = 4,
    ncol = 3,
    dimnames = list(
      paste0("v", 1:4),
      paste0("h", 1:3)
    )
  )
)
hype2 <- hype_from_inc_mat(i2)
hype3 <- hype_from_inc_mat(i2, directed = TRUE)
