get_adjacency.default

Description

A fct that build an adjacency matrix from a list of edges

Usage

## Default S3 method:
get_adjacency(edges, type = c("unipartite", "bipartite"), directed = FALSE)

Arguments

edges

Can be a table which is a list pair of nodes (nodes ids are one the two first columns) a numerical third column can be associated will be the connections values.

type

network type can be ''bipartite'‘ or '’unipartite''

directed

whether or not connections are directed ('TRUE') or symmetrical ('FALSE') (default is set to 'TRUE')

Value

an adjacency/incidence matrix (data.frame) representing the network

Examples

# For unipartite network
data_uni <- FungusTreeNetwork$networks$tree_tree

# If the network is symmetric:
my_mat <- get_adjacency(data_uni$edges,
  type = data_uni$type,
  directed = FALSE
)
# If the network is directed:
my_mat <- get_adjacency(data_uni$edges,
  type = data_uni$type,
  directed = TRUE
)

# For bipartite network
data_bi <- FungusTreeNetwork$networks$fungus_tree

my_mat <- get_adjacency(data_bi$edges, type = data_bi$type)

# In any case with a 2 columns data.frames the network is considered binary and each line is a 1.
binary_net <- FungusTreeNetwork$fungus_tree$edges[, -3]

my_mat <- get_adjacency(binary_net, type = data_bi$type)
