R/writing_tools.R
gephi_write_nodes.Rdwrite_nodes will write the nodes, and write_edges will write the edges to a csv file. You will alway want to use the write_edges function, the write nodes function has only added value if the nodes have attributes, such as Label, Age, color etc.
gephi_write_nodes(graph, path, na = "", verbose = TRUE) gephi_write_edges(graph, path, na = "", verbose = TRUE) gephi_write_both(graph, pathedges, pathnodes, na = "", verbose = TRUE)
| graph | The igraph or tidygraph object your work with |
|---|---|
| path | the file where to save to e.g.: edges.csv or data/edges.csv |
| na | How to record missing values, defaults to "", nothing / empty values |
| verbose | by default these functions are chatty and will tell you what they do if you do not want that, set to FALSE |
| pathedges | where to save the edges file e.g.: 'edges.csv' |
| pathnodes | where to save the nodes file e.g.: 'nodes.csv' |
invisible original object so you could continue using it in a pipe if you want to
If the file is not an igraph / tidygraph object, but a dataframe you could use the write_*_from_df functions. This function will assume the edges are between the first and second column, but you can specify if that is not the case.
gephi_write_edges: Write nodes data to csv
gephi_write_both: Write both node and edge data away
