bipartite_from_data_frame: two-mode network from a data.frame

In netUtils: A Collection of Tools for Network Analysis

two-mode network from a data.frame

Description

Create a two-mode network from a data.frame

Usage

bipartite_from_data_frame(d, type1, type2, attr = NULL, weighted = TRUE)

Arguments

d	data.frame
type1	column name of mode 1
type2	column name of mode 2
attr	named list of edge attributes
weighted	should a weighted graph be created if multiple edges occur

Details

Vertex identifiers are converted to character, so numeric and factor columns are matched by their values. If weighted = TRUE, multiple edges are merged, their count is stored in the edge attribute weight, numeric edge attributes are summed and other edge attributes keep their first value.

Value

two mode network as igraph object. The vertex attribute type is TRUE for vertices from type1 and FALSE for vertices from type2.

edges <- data.frame(mode1 = 1:5, mode2 = letters[1:5])
