to_graphml: Export to GraphML

In bibnets: Importing, Constructing, and Exporting Bibliometric Networks

Export to GraphML

Description

Writes a bibnets edge list (and optional node attributes) to a GraphML file using pure base R — no XML package required.

Usage

to_graphml(edges, nodes = NULL, file = NULL, directed = FALSE)

Arguments

edges	A data frame with at least from, to, weight columns.
nodes	Optional data frame of node attributes with an id column.
file	File path to write. If NULL (default), returns the GraphML as a character string.
directed	Logical. Default FALSE.

Value

If file = NULL: GraphML as a character string. Otherwise writes the file and returns the path invisibly.

Examples

data(biblio_data)
edges <- keyword_network(biblio_data)
xml <- to_graphml(edges)
cat(substr(xml, 1, 300))
