Write Gephi-Friendly .graphml Files

Simple, safe transformation of attributes to values with which Gephi will cooperate.

write_graphml(g, file_path, na_numbers_as = -1, na_characters_as = "", ...)

Arguments

g	igraph::graph() object
file_path	File path to which to write or from which to read.
na_numbers_as	numeric(1L), Default: -1. Value to replace NA_real_/NA_integer_s in the resulting file.
na_characters_as	character(1L), Default: "". Value to replace NA_character_s in the resulting file.
...	Arguments passed to or from other methods.

Examples

path_to_tweet_file <- example_tweet_file()

tweet_df <- read_tweets(file_path = path_to_tweet_file)

tweet_graph <- as_igraph(tweet_df)
