A stat for fitting distributions — stat

This stat computes points for plotting a distribution function. Fitting is done using MASS::fitdistr() when analytic solutions are not available.

Usage

stat_fitdistr(
  mapping = NULL,
  data = NULL,
  geom = "path",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  dist = "dnorm",
  start = NULL,
  ...
)

Arguments

mapping: Aesthetics created using aes() or aes_string().
data: A data frame.
geom: A character string naming the geom used to make the layer.
position: Either a character string naming the position function used for the layer or a position object returned from a call to a position function.
na.rm: If TRUE, do not emit a warning about missing data.
show.legend: A 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.
dist: A character string indicating the distribution to fit. Examples include "dnorm", "dgamma", etc.
start: A list of starting values used by MASS::fitdistr() when numerically approximating the maximum likelihood estimate.
...: Additional arguments.

Value

A gg object
