A fct that build an adjacency matrix from a list of edges.
Usage
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`)
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)
#> Warning: edges should be a table of 2 or 3 columns
