Color edges by nodegroups

Color edges by nodegroups

Usage

color_nodes_by_nodegroups(
  g,
  nodegroups = NULL,
  nodegroup_colors = NULL,
  node_alpha = NULL,
  Crange = NULL,
  Lrange = NULL,
  color_attributes = c("color"),
  verbose = FALSE,
  ...
)

Arguments

g

igraph object that contains vertex node attribute "color" as seen with igraph::vertex_attr(g, "color").

nodegroups

list or communities object that references nodes in g and assigns one or more to nodegroups. Default NULL calls get_cnet_nodeset(), passing '...' for customization.

nodegroup_colors

character or default NULL which assigns categorical colors by colorjam::rainbowJam().

node_alpha

numeric of default NULL uses 1, with opacity where 0 is transparent, 1 is completely solid.

Crange, Lrange

numeric ranges passed to colorjam::rainbowJam() to restrict the chroma and luminance of categorical colors. Default NULL uses the defaults in colorjam::rainbowJam().

color_attributes

character vector of node attributes to assign new colors, default 'color' assigns color to the node itself. Note that this color is not seen when shape is 'pie' or 'jampie', instead use 'pie.color'.

verbose

logical indicating whether to print verbose output.

...

additional arguments are passed tocolorjam::rainbowJam(), notably 'preset' which defines the color wheel used.

Value

igraph object with edge color attribute updated to represent the result of blending node colors, seen by igraph::edge_attr(g)$color.

Examples

cnet1 <- make_cnet_test()
igraph::vertex_attr(cnet1, "shape") <- "circle";
cnet2 <- color_nodes_by_nodegroups(cnet1);
# behold color
jam_igraph(cnet2)


# you can enable mark.groups which uses the same colorjam::rainbowJam()
jam_igraph(cnet2, mark.groups=TRUE)
