[R] igraph: error when setting size and shape of vertices

When the shape of all vertices is set to "square" and the size of the vertices is also set, one get following error (commands attached): Error in l[[which.min(sapply(l, function(p) (p[1] - x0)^2 + (p[2] - y0)^2))]] : attempt to select less than one element Is there a way to solve this pr

Re: [R] title second y-axis in lattice plot

Thanks Deepayan, The following code solves the problem until 'ylab.right' will be implemented. Robbie library(lattice) library(grid) g1<-textGrob("axis title at right", x = unit(0.5, "npc"), y = unit(0.5, "npc"), just = "centre", hjust = NULL, vjust = NULL, rot = 270, check

[R] title second y-axis in lattice plot

Dear R-users, After adding the secondary y-axis at the right side of a lattice xyplot (cfr. Lattice: Multivariate Data Visualization with R - figures 8.4 and 8.6, from http://lmdvr.r-forge.r-project.org/figures/figures.html), I'm trying to add a title to that second y-axis (which has to be dif
