In ijlyttle/colorpath: Build Color Paths

Color-vision deficiency grid

Description

Helper functions to generate grid for color-vision deficiency (CVD) possibilities. These functions do the same thing, but have different default values.

Usage

pth_cvd_grid(condition = c("none", "deutan", "protan", "tritan"), severity = 1)

pth_cvd_grid_full(
  condition = c("deutan", "protan", "tritan"),
  severity = c(0, 0.33, 0.67, 1)
)

pth_cvd_grid_none(condition = "none", severity = 0)

pth_cvd_grid_severity(severity = 1)

pth_cvd_grid_deupro(
  condition = c("deutan", "protan"),
  severity = seq(0, 1, by = 0.1)
)

Arguments

condition	character one or more color-vision deficiency conditions; legal values: "none", "deutan", "protan", "tritan".
severity	double one or more values of severity for a given condition; legal values from 0 to 1.

Details

pth_cvd_grid()

All cases, including "none", at maximum severity.

pth_cvd_grid_full()

All CVD cases, at four values of severity.

pth_cvd_grid_none()

No CVD cases, zero severity.

pth_cvd_grid_severity()

Useful for evaluating performance of categorical palettes, concatenates result of pth_cvd_grid_none() with pth_cvd_grid_severity()

.

pth_cvd_grid_deupro()

Useful for choosing colors in categorical palettes, Deutan and Protan CVD cases, severity from zero to one.

Value

tbl_df with columns cvd (factor), severity (double)

Examples

  pth_cvd_grid_none()
  pth_cvd_grid_full()
  pth_cvd_grid_severity(0.9)
