MLB Spraychart

Description

This generates a spraychart - a scatter plot of x, y values overlayed on a baseball field. It effectively overrides geom_point and additionally concatenates a geom_mlb_stadium layer.

Usage

geom_spraychart(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", na.rm = FALSE, show.legend = NA,
  inherit.aes = TRUE, stadium_aes = NULL, stadium_ids = NULL,
  stadium_segments = "outfield_outer", stadium_transform_coords = FALSE,
  ...)

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. There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot. A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify for which variables will be created. A function will be called with a single argument, the plot data. The return value must be a data.frame., and will be used as the layer data.
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.
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 behavior from the default plot specification, e.g. borders.
stadium_aes	mapping to pass to geom_mlb_stadium
stadium_ids	character Vector of stadium ids.
stadium_segments	character Vector of stadium_segments to display. Options are 'outfield_inner', 'outfield_outer', 'infield_inner', 'infield_outer', 'foul_lines', 'home_plate', 'all'.
stadium_transform_coords	boolean if TRUE, then transform the path data according to mlb_xy_transformation
...	other arguments passed on to layer. These are often aesthetics, used to set an aesthetic to a fixed value, like color = "red" or size = 3. They may also be parameters to the paired geom/stat.

Examples

g = ggplot() + geom_mlb_
set.seed(101)
batted_ball_data = data.frame(hc_x = rnorm(20, 125, 10), hc_y=rnorm(20, 100, 20))
batted_ball_data$team = rep(c("angels", "yankees"), each=10)
g <- ggplot(batted_ball_data) + geom_spraychart()
