An igraph graph object. The good news is: not all functions in igraph have bad performance. Due to its versatility and rich set of functions igraph leads in acceptance and importance. Note that the arguments will be serialized and saved to a file, so if they are large R objects, it might take a long time for the child process to start up. It may be something like this: Installing package(s) into ‘D:/R/library’(as ‘lib’ is unspecified) …. This function should not be used directly by igraph users, it is useful only in the case when the underlying igraph object must be passed to other C code through Python. Many thanks in advance, Brock. While this will display the node names, you can't use it as a vector. In this case there are likely to be very many words total, and the following visualization will not necessarily be sensible without judicious data trimming.
