Hi: I want to create a polygon encircling a graph. For this i use convex hull to get the coordinate points for polygon.
g <- barabasi.game(10) L<-layout.fruchterman.reingold(g) temp1 <- chull(L) temp1 <- c(temp1, temp1[1]) plot(g, layout=layout.fruchterman.reingold) But when i plot the polygon with the code below, the polygon dosen't encircle the graph. polygon(L[temp1, ], col = "#0000FFAA") How can I plot a polygon circling a graph?
