Hi Richard,

node components... the output of the igraph_clusters routine seems to
report this.  Is there a work around or a routine to re-sequence the
node numbers in igraph?
Use the output of igraph_degree to detect isolated vertices (with degree 0) and then use igraph_subgraph to get rid of them. Of course this works only if there were no isolated vertices in the original dataset, otherwise it would remove those as well.
