Connect points to their centroid

stat_centroid.Rd

Connect points to their centroid.

Usage

stat_centroid(
  mapping = NULL,
  data = NULL,
  geom = "segment",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  cfun = mean,
  ...
)

Arguments

mapping

Set of aesthetic mappings created by aes() or aes_(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.

data

The data to be displayed in this layer. If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot().

geom

Use to override the default Geom

position

Use to override the default position

na.rm

If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.

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. It can also be a named logical vector to finely select the aesthetics to display.

inherit.aes

TRUE or FALSE. If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification.

cfun

Function used to calculate centroid location.
