Export to Gephi node and edge tables

Converts a bibnets edge list (and optional node table) to the CSV format expected by Gephi's Data Laboratory. Column names are remapped to Gephi conventions (Source, Target, Weight, Id, Label).

Usage

to_gephi(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. Must contain an id column. All other columns are included as Gephi node attributes.

file

Optional directory path. If supplied, writes nodes.csv and edges.csv into that directory. If NULL (default), returns a list.

directed

Logical. Sets the Type column. Default FALSE.

Value

If file = NULL: a list with $nodes and $edges data frames. If file is a directory path: writes two CSV files invisibly and returns the file paths.

Examples

data(biblio_data)
edges <- author_network(biblio_data, "collaboration")
gephi <- to_gephi(edges)
head(gephi$edges)
