[R] vertical slices in persp or drape.plot

Hi List, I want to show three matrices in a 3D plot, one horizontal, and the other two as vertical slices. Ideally this would use the persp or drape.plot functions. I have found a means of assigning one matrix to the lower xy plane (like a carpet), thus: mat_2D <- matrix(runif(100),nrow=10,ncol=1

[R] igraph question

Hi List, I have a set of small graphs with weighted and directed edges (< 40 vertices each). As igraph's 'transitivity' function ignores the edge weight & direction, I wonder if there's any method for estimating the global clustering coefficient for such graphs..? Cheers, Tom -- View this me
