functions to manipulate an existing layout

layout_rotate(xy, angle)

layout_mirror(xy, axis = "vertical")

Arguments

xy

graph layout

angle

angle for rotation

axis

mirror horizontal or vertical

Value

manipulated matrix of xy coordinates

Details

These functions are mostly useful for deterministic layouts such as layout_with_stress

Examples

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")
