gl.colors {dartR.base}

Returns a list of colors for use in plots

Description

Creates a vector of colors in hex (e.g. "#3B9AB2" "#78B7C5") based on user selected category (parameter type).

• "2" [two colors]

• "2c" [two colors contrast]

• "3" [three colors]

• 4" [four colors]

• "pal" [need to be specify the palette type and the number of colors]

A palette of colors can be specified via "div" [divergent], "dis" [discrete], "con" [convergent], "vir" [viridis]. Be aware a palette needs the number of colors specified as well. It returns a function and therefore the number of colors needs to be a part of the function call. Check the examples to see how this works.
