Valence layout

The "valence" layout places the nodes of a signed network so that positively tied nodes are drawn together and negatively tied nodes apart.

Usage

layout_valence(
  .data,
  times = 500,
  center = NULL,
  circular = FALSE,
  repulsion_coef = 1,
  attraction_coef = 0.05
)

layout_tbl_graph_valence(
  .data,
  times = 500,
  center = NULL,
  circular = FALSE,
  repulsion_coef = 1,
  attraction_coef = 0.05
)

Arguments

.data

Some {manynet} compatible network data.

times

Maximum number of iterations, where appropriate. Required for {ggraph} compatibility, and ignored by the layouts that do not iterate.

center

Required for {ggraph} compatibility, and not used here.

circular

Should the layout be transformed into a radial representation. Only possible for some layouts. Defaults to FALSE. Required for {ggraph} compatibility.

repulsion_coef

Coefficient for global repulsion force. Default is 1.

attraction_coef

Coefficient for edge-based attraction/repulsion force. Default is 0.05.

Value

Returns a table of nodes' x and y coordinates.

Examples

edges <- data.frame(
  from = c("A", "B", "C", "D"),
  to   = c("B", "C", "D", "A"),
  weight = c(2, 3, 1, 4),
  sign = c(1, -1, 1, -1)  # 1 = positive, -1 = negative
  )
graphr(as_igraph(edges), layout="valence")
