Conversion from data.frame to adjacency matrix

Description

Creates an adjacency matrix from an edge list data.frame.

Usage

df.to.adjacency(
  df,
  source.column = "source",
  target.column = "target",
  value.column = "value"
)

Arguments

df	data.frame containing edge data
source.column	Name of column containing source nodes. Defaults to "source".
target.column	Name of column containing target nodes. Defaults to "target".
value.column	Name of column containing edge values. Defaults to "value".

Value

A list with two components:

matrix	Adjacency matrix
labels	Names of nodes, in same order as rows/columns of adjacency matrix

Examples

labels = c("spam", "eggs", "foo", "bar")

df = data.frame(source = rep(labels, each = 4),
                target = rep(labels, times = 4),
                value = c(11975, 5871, 8916, 2868,
                          1951, 10048, 2060, 6171,

                          1013, 990, 940, 6907))
