write.graph
is a general function for exporting
graphs to foreign file formats, however not many formats are
implemented right now.write.graph(graph, file, format="edgelist", ...)
edgelist
, lgl
and ncol
are implemented.NULL
edgelist
format is a simple text file, with one edge in a
line, the two vertex ids separated by a space character. The file is
sorted by the first and the second column. The lgl
format is also a simple text file, this is the
format expected by the 'Large Graph Layout' layout generator software.
See read.graph for details.
Additional arguments:
NULL
if you want to use numeric
vertex ids even if there is a NULL
here if you want to omit the weights.}
TRUE
the isolate vertices are
also written to the file, they are omitted by default.}read.graph
g <- graph.ring(10)
write.graph(g, "/tmp/g.txt", "edgelist")
