Make a network object from various input types.
to_network(x, bipartite = FALSE)
a network
object
The following inputs are supported:
network
objectnetwork
object
igraph
objectigraph
object
matrix
This is a base R type matrix
.
When a matrix is used as input,
the function the number of rows is equal to the number of columns.
If they are not, the function assumes the matrix refers to a bipartite network.
This assumption can be overridden by the bipartite
argument.
data.frame
The data.frame
contains an edge list.
The data.frame requires the first column to contain the senders and the
second column contains the receivers. If there are any additional
columns, these are considered to be edge attributes.
NOTE: The created network
object is considered to be directed.
If an undirected network is required, run as.undirected
on the output from this function.
The argument bipartite
is used to tell the function whether the input
represents a bipartite network or not. If it does, then set bipartite
to TRUE
and the function will attempt to convert the input to a
bipartite network.
However, the argument is NOT intended to convert a bipartite network to
a unipartite network and will NOT do that conversion!
NOTE: as far as we know, this function is the only function that correctly
deals with vertex attributes that themselves are lists in the conversion
from igraph
(which allows lists) to network
(which can not
deal with lists as attributes).
