Sketchy histogram and frequency polygon

Source: R/geom-sketch-histogram.R
geom_sketch_histogram.Rd

geom_sketch_histogram() bins a continuous variable and draws hand-drawn bars (the sketch analogue of ggplot2::geom_histogram()). geom_sketch_freqpoly() draws the same bin counts as a roughened line (ggplot2::geom_freqpoly()).

Usage

geom_sketch_histogram(
  mapping = NULL,
  data = NULL,
  stat = "bin",
  position = "stack",
  ...,
  bins = 30,
  binwidth = NULL,
  roughness = 1,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  fill_style = "hachure",
  hachure_angle = 45,
  hachure_gap = NULL,
  fill_weight = 0.5,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

geom_sketch_freqpoly(
  mapping = NULL,
  data = NULL,
  stat = "bin",
  position = "identity",
  ...,
  bins = 30,
  binwidth = NULL,
  roughness = 1,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping

Set of aesthetic mappings created by ggplot2::aes().

data

Data to display.

stat

Statistical transformation. Default "identity" for geom_sketch_col(); "count" for geom_sketch_bar().

position

Position adjustment. Default "stack".

...

Other arguments passed on to the layer.

bins

Number of bins (passed to ggplot2::stat_bin()). Default 30.

binwidth

Bin width; overrides bins when supplied.

roughness

Non-negative roughness (0 = straight lines). A mappable aesthetic (default 1): pass a constant, or map it per bar with aes(roughness = ) (rescaled by scale_roughness_continuous()).

bowing

Non-negative bowing multiplier. Default 1.

n_passes

Number of stroke passes. Default 2.

seed

Integer seed. NULL uses getOption("ggsketch.seed", 1L).

fill_style

One of "hachure", "cross_hatch", "zigzag", "zigzag_line", "scribble", "dots", "dashed", "stipple", "pencil_shade", or "solid". Default "hachure".

hachure_angle

Fill line angle in degrees. Default 45.

hachure_gap

Fill line gap in device inches (NULL = 15% of the bar's smaller drawn side, clamped to [0.04, 0.4] inches).

fill_weight

Stroke weight for fill lines. Default 0.5.

na.rm

Remove missing values silently? Default FALSE.

show.legend

Logical; include in legend?

inherit.aes

Override default aesthetics?

Value

A ggplot2 layer object.
