[R] Finding the package providing funtion "%du%"

[Federico Calboli]

Hello All,

I am playing with igraph (which seems to work for what I have used it).  Nevetheless:

demo('community', package="igraph")



	demo(community)
	---- ~~~~~~~~~

Type  <Return>	 to start : 

> pause <- function() {}

> ### A modular graph has dense subgraphs
> mod <- make_full_graph(10) %du% make_full_graph(10) %du% make_full_graph(10)
Error in make_full_graph(10) %du% make_full_graph(10) %du% make_full_graph(10) : 
 could not find function "%du%”


For the life of mine I cannot find where %du5 is meant to come from.  Any clues?  also, any suggestion 9other than Google) to *efficiently* find whatever dependencies I might be missing?  I did install igraph with dependencies = T… but one never knows.
