Visualize College Basketball Conference Logos in ggplot2

Source: R/geom_cbb_conferences.R
geom_cbb_conferences.Rd

geom_cbb_conferences creates a ggplot2 layer that plots college basketball conference logos in place of points. The layer requires x and y aesthetics and a valid conference name. The width parameter can be used to adjust the size of the logos. Logos can be depicted as either normal or wordmark by setting the logo_type parameter.

Usage

geom_cbb_conferences(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  na.rm = FALSE,
  show.legend = FALSE,
  inherit.aes = TRUE,
  logo_type = "normal",
  highlight_conferences = NULL,
  highlight_method = "alpha",
  highlight_alpha = 0.5
)

Arguments

mapping

Set of aesthetic mappings created by ggplot2::aes() or ggplot2::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().

stat

The statistical transformation to use on the data for this layer, as a string.

position

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

...

Other arguments passed on to layer().

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.

inherit.aes

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, e.g. borders().

logo_type

Character specifying the type of logos to plot ("normal" or "wordmark").

highlight_conferences

Vector of conference names to highlight.

highlight_method

Method of highlighting ("alpha", "color", or "both").

highlight_alpha

Alpha value for highlighted conferences.

Value

A ggplot2 layer that can be added to a plot created with ggplot().

Aesthetics

This geom requires the following aesthetics:

  • x - The x-coordinate for the logo's position.

  • y - The y-coordinate for the logo's position.

  • conference - The name of the conference, which should be a valid name from cbbdata.
