geom_node_circle

Percentile

Show nodes as circles

This geom is equivalent in functionality to geom_circle and allows for plotting of nodes as circles with a radius scaled by the coordinate system. Beceause of the geoms reliance on the coordinate system it will only produce true circles when combined with coord_fixed

Usage
geom_node_circle(mapping = NULL, data = NULL, position = "identity",
  show.legend = NA, ...)
Arguments
mapping

Set of aesthetic mappings created by aes or aes_. By default x and y are mapped to x0 and y0 in the node data.

data

A data frame. If specified, overrides the default data frame defined at the top level of the plot.

position

Position adjustment, either as a string, or the result of a call to a position adjustment function.

show.legend

logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.

...

other arguments passed on to layer. There are three types of arguments you can use here:

  • Aesthetics: to set an aesthetic to a fixed value, like color = "red" or size = 3.

  • Other arguments to the layer, for example you override the default stat associated with the layer.

  • Other arguments passed on to the stat.

Aesthetics

geom_node_point understand the following aesthetics. Bold aesthetics are automatically set, but can be overridden.

  • x0

  • y0

  • r

  • alpha

  • colour

  • fill

  • shape

  • size

  • stroke

  • filter
