Read files of 'graph6', 'sparse6' or 'digraph6' symbols

Usage

read_file6(path, type = "adjacency")

Arguments

path: character; path to file name
type: character; one of "adjacency", "edgelist", "igraph", or "network". Type of result returned.

Value

A list of decoded graphs in the form of objects determined by type.

Details

File pointed to by path is a text file with one graph symbol per line. Optional headers of the form >>graph6<< or >>sparse6<< in the first line (and without the newline after the header) are ignored and removed.

Examples

g6_file <- tempfile()
write(sampleg6,g6_file)
read_file6(g6_file, type = "adjacency")
