Calculation of all pieces necessary to plot a logo sequence plot

Usage

StatLogo

stat_logo(
  mapping = NULL,
  data = NULL,
  geom = "logo",
  position = "logo",
  show.legend = NA,
  inherit.aes = TRUE,
  width = 0.9,
  na.rm = TRUE,
  ...
)

Format

An object of class StatLogo (inherits from Stat, ggproto, gg) of length 4.

Arguments

mapping: The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data: A layer specific dataset - only needed if you want to override the plot defaults,
geom: The geometric object to use display the data,
position: The position adjustment to use for overlappling points on this layer,
show.legend: Whether to show the legend or not
inherit.aes: Whether to inherit the aes or not
width: maximum width of the letters, defaults to 0.9,
na.rm: Whether to remove NAs or not
...: other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.

Value

proto object

A proto object
