write.pajek.bgraph {igraph} | R Documentation |
Creates a series of Pajek-compatible files from a bgraph
object
as output by cohesive.blocks
.
write.pajek.bgraph(graph, filename, hierarchy = FALSE)
graph |
A |
filename |
The filename without file extension to use. |
hierarchy |
Logical. Should a separate |
This function writes at least two files to disk. First, the file
filename.net
contains the basic graph structure—vertices and
edges. The second is the file filename.clu
, which clusters the
vertices according to vertex connectivity of their maxmally cohesive
subgraph. This uses the same logic as the default vertex coloring in
plot.bgraph
.
If hierarchy
is TRUE
, more detailed and complete
information is written to a further series of files.
For each block a seperate .clu
file is written, each named like
“filename_block2(1).clu
”, where the first number refers to the
block number and the number in parenthesis refers to that block's
cohesion. Finally, if hierarchy
is TRUE
, a tree
representing the block hierarchy is written to
filename_blocktree.net
, allowing the subset-structure of the
individual block structures to be determined.
This function has not been thoroughly tested, and may contain bugs
