functions to manipulate an existing layout
layout_rotate(xy, angle)
layout_mirror(xy, axis = "vertical")graph layout
angle for rotation
mirror horizontal or vertical
manipulated matrix of xy coordinates
These functions are mostly useful for deterministic layouts such as layout_with_stress
library(igraph)
g <- sample_gnp(50,0.3)
xy <- layout_with_stress(g)
#rotate 90 degrees
xy <- layout_rotate(xy,90)
# flip horizontally
xy <- layout_mirror(xy,"horizontal")
