layout_with_gem | R Documentation |
Place vertices on the plane using the GEM force-directed layout algorithm.

coords = NULL,
maxiter = 40 * vcount(graph)^2,

temp.init = sqrt(max(vcount(graph), 1))

graph |
The input graph. Edge directions are ignored. |
coords |
If not |
maxiter |
The maximum number of iterations to perform. Updating a single vertex counts as an iteration. A reasonable default is 40 * n * n, where n is the number of vertices. The original paper suggests 4 * n * n, but this usually only works if the other parameters are set up carefully. |
temp.max |
The maximum allowed local temperature. A reasonable default is the number of vertices. |
temp.min |
The global temperature at which the algorithm terminates
(even before reaching |
temp.init |
Initial local temperature of all vertices. A reasonable default is the square root of the number of vertices. |

See the referenced paper below for the details of the algorithm.
A numeric matrix with two columns, and as many rows as the number of vertices.
