layout_manipulate function

manipulate layout

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

Returns

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")
