Get a built-in colour scheme

Returns the category-colour and diverging-link-palette definition for a built-in scheme, so you can inspect it or tweak a copy before passing it to corr_wheel()'s scheme argument.

Usage

corr_wheel_scheme(name = "default")

Arguments

name

A scheme name; see corr_wheel_schemes() for the available options.

Value

A list with elements colors (an unnamed vector of category colours, cycled across however many categories are plotted) and palette (a length-3 diverging colour vector: negative, midpoint, positive).

Examples

s <- corr_wheel_scheme("colorblind")
s$palette
#> [1] "#E66101" "#F7F7F7" "#5E3C99"

# Tweak a copy and use it
s$palette[2] <- "grey95"
data(gastro_symptoms)
grp <- list(Demographics = c("Age", "BMI"),
           Metrics = c("Amplitude", "Fed-Fasted AR", "Frequency", "GA-RI"))
if (requireNamespace("psych", quietly = TRUE)) {
  corr_wheel(gastro_symptoms, groups = grp, scheme = s, r_threshold = 0)
}
