scale_shape_calc: Calc shape scale

In ggthemes: Extra Themes, Scales and Geoms for 'ggplot2'

Calc shape scale

Description

See calc_shape_pal() for details.

Usage

scale_shape_calc(..., unicode = FALSE)

Arguments

...

Arguments passed on to discrete_scale breaks One of: NULL for no breaks waiver() for the default breaks (the scale limits) A character vector of breaks A function that takes the limits as input and returns breaks as output. Also accepts rlang lambda function notation. limits One of: NULL to use the default scale values A character vector that defines possible values of the scale and their order A function that accepts the existing (automatic) values and returns new ones. Also accepts rlang lambda function notation. drop Should unused factor levels be omitted from the scale? The default, TRUE, uses the levels that appear in the data; FALSE includes the levels in the factor. Please note that to display every level in a legend, the layer should use show.legend = TRUE. na.translate Unlike continuous scales, discrete scales can easily show missing values, and do so by default. If you want to remove missing values from a discrete scale, specify na.translate = FALSE. na.value If na.translate = TRUE, what aesthetic value should the missing values be displayed as? Does not apply to position scales where NA is always placed at the far right. aesthetics The names of the aesthetics that this scale works with. minor_breaks One of: NULL for no minor breaks waiver() for the default breaks (none for discrete, one minor break between each major break for continuous) A numeric vector of positions A function that given the limits returns a vector of minor breaks. Also accepts rlang lambda function notation. When the function has two arguments, it will be given the limits and major break positions. labels One of the options below. Please note that when labels is a vector, it is highly recommended to also set the breaks argument as a vector to protect against unintended mismatches. NULL for no labels waiver() for the default labels computed by the transformation object A character vector giving labels (must be same length as breaks) An expression vector (must be the same length as breaks). See ?plotmath for details. A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation. call The call used to construct the scale for reporting messages. super The super class to use for the constructed scale

unicode

If TRUE, return pch codes derived from Unicode glyphs, as this palette did before ggthemes 6.1.0. Glyph shapes are drawn by the device font, so they render as blank boxes in a font without coverage; the default returns base pch codes, which every font can draw.

Value

A ggplot2 scale object.
