Hi Subsequent to updating to the latest version of igraph I get the error message:
"Error in seq_len(no) : argument must be coercible to non-negative integer" when creating an igraph object with certain attribute characteristics (ie many attributes) the error is generated. I have tried to pin down the cause and have failed to do so but does seem to be associated with the number of edge or vertex attributes (80+). Interestingly, changing the method of creating attributes from add.vertices to assigning values directly to the graph (eg V(g)$numeric <- c(1,2,3,4)) alleviates this problem some of the time, but not all the time. I attempted to create some code to reproduce in toy example but have failed. In short the code worked in previous version and now does not so I am assuming it is a bug.
