Create a factor variable for the different age categories, see cut(). Then use as.integer() on the factor variable and index a vector of node sizes with it. E.g.
g <- graph.ring(10) V(g)$age <- sample(20:78, vcount(g), replace=TRUE) V(g)$agecat <- cut(V(g)$age, breaks = c(20,35,50,65,78)) V(g)$size <- c(10,15,20,25)[ V(g)$agecat ] plot(g, layout=layout.circle) Best, Gabor On Wed, Aug 10, 2011 at 1:38 PM, Gaitan, Andreea <andreea.gaita...@imperial.ac.uk> wrote: > Hi, > > I'm working on some social networks and I managed to create the graphs with > labels and edges weight, but I would also like to change the size of the > vertices according to the age of the persons in the network and the shape > according to the gender.
