Description

Adds a fish silhouette to your plot

Usage

add_fishape(
  family = "Pomacanthidae",
  option = "Centropyge_loricula",
  xmin = -Inf,
  xmax = Inf,
  ymin = -Inf,
  ymax = Inf,
  scaled = FALSE,
  xlim = NULL,
  ylim = NULL,
  fill = "#000000",
  alpha = 1
)

Arguments

family	character string indicating the fish family.
option	character string indicating the fish species. If NA, the first available option within a family will be selected
xmin	x location giving minimum horizontal location of silhouette
xmax	x location giving maximum horizontal location of silhouette
ymin	y location giving minimum vertical location of silhouette
ymax	y location giving maximum vertical location of silhouette
scaled	logical parameter. If TRUE, location parameters (xmin, xmax, ymin, ymax) should range between 0 and 1. If FALSE, location parameters should be provided according to the values on the plot axes.
xlim, ylim	vectors of length = 2, contains the data limits and must be provided if scaled is TRUE.
fill	color of fish shape
alpha	transparency of fish shape (value between 0 and 1)

Value

Adds a fish silhouette grob to a ggplot object.
