JASP color palettes

JASPcolors(palette = getGraphOption("palette"), asFunction = FALSE)

scale_JASPcolor_continuous(palette = getGraphOption("palette"), ...)

scale_JASPfill_continuous(palette = getGraphOption("palette"), ...)

scale_JASPcolor_discrete(palette = getGraphOption("palette"), ...)

scale_JASPfill_discrete(palette = getGraphOption("palette"), ...)

Arguments

palette: Palette to choose from.
asFunction: Should a function be returned or the raw colors? If a function is returned, it either takes a single integer or a vector in 0, 1 as input.
...: Further arguments for scale_colour_continuous.

Value

Either a character vector of colors or a function.

Details

For ggplot2s, the convenience functions scale_JASPcolor_\* and scale_JASPfill_\* exist.

Examples

# use colors directly

# use a function if you want an arbitrary number of colros
colFun <- JASPcolors(palette = "colorblind", asFunction = TRUE)

# use colorscales in ggplot2

g1 + scale_JASPcolor_discrete() + scale_JASPfill_discrete()


# colorblind is not really suited for a continuous color scale
g0 + scale_JASPcolor_continuous() + scale_JASPfill_continuous()


# viridis already looks a lot better!
setGraphOption("palette", "viridis")
g0 + scale_JASPcolor_continuous() + scale_JASPfill_continuous()


# reset the palette to it's default if you changed it globally!
