Generate a ggplot2 instance containing a football field for a specified league

Usage

geom_football(
  league,
  display_range = "full",
  field_updates = list(),
  color_updates = list(),
  rotation = 0,
  x_trans = 0,
  y_trans = 0,
  field_units = NULL,
  xlims = NULL,
  ylims = NULL
)

Arguments

league

The league for which to draw the surface. This is case-insensitive

display_range

A case-insensitive string indicating the display range to use for the plot. The default is "full", which will be returned when either an invalid or no value is passed to the function.

The possible display ranges are:

"full"

The full field. This is the default

"offense"

The TV-right half of the field

"offence"

The TV-right half of the field

"offensivehalffield"

The TV-right half of the field

"offensive_half_field"

The TV-right half of the field

"offensive half field"

The TV-right half of the field

"defense"

The TV-left half of the field

"defence"

The TV-left half of the field

"defensivehalffield"

The TV-left half of the field

"defensive_half_field"

The TV-left half of the field

"defensive half field"

The TV-left half of the field

"redzone"

The offensive red zone of the field. This is by definition 20 yards from the goal line

"red_zone"

The offensive red zone of the field. This is by definition 20 yards from the goal line

"red zone"

The offensive red zone of the field. This is by definition 20 yards from the goal line

"oredzone"

The offensive red zone of the field. This is by definition 20 yards from the goal line

"offensive_red_zone"

The offensive red zone of the field. This is by definition 20 yards from the goal line

"offensive red zone"

The offensive red zone of the field. This is by definition 20 yards from the goal line

"dredzone"

The defensive red zone of the field. This is by definition 20 yards from the goal line

"defensive_red_zone"

The defensive red zone of the field. This is by definition 20 yards from the goal line

"defensive red zone"

The defensive red zone of the field. This is by definition 20 yards from the goal line

field_updates

A list of updates to the field's parameters. These will overwrite the parameters of the league

color_updates

A list of updates to the field's default colors, which are set by football_features_set_colors()

rotation

An angle, given in degrees, through which the plot should be rotated

x_trans

The amount that the x coordinates are to be shifted. By convention, the +x axis extends from the center of the field towards the right-hand endzone when viewing the field in TV View

y_trans

The amount that the y coordinates are to be shifted. By convention, the +y axis extends from the center of the field towards the sideline when viewing the field in TV view

field_units

The units with which to draw the field. The default is NULL, which will apply the rule-book specified units

xlims

The limits on the final display in the x direction. The default is NULL, which will utilize the xlims specified by the display_range parameter

ylims

The limits on the final display in the y direction. The default is NULL, which will utilize the ylims specified by the display_range parameter

Value

A ggplot2 instance with a full-surface representation of a football field

Examples

if (FALSE) {
  geom_football(league = "NFL", rotation = 270, display_range = "red_zone")
  geom_football(league = "cfl", field_units = "ft")
}
