bi_pal_manual

Create Manual Palette

Description

A function for structuring manual bi-variate palettes. All values must be entered as six-digit hex values (e.g. #000000) and must be preceded by the number symbol. Short forms of hex values (e.g. #000) are not accepted as valid inputs. For two-by-two palettes, only the 'val_1_1', 'val_1_2', 'val_2_1', and 'val_2_2' parameters are required. For three-by-three palettes, all parameters are required.

Usage

bi_pal_manual(val_1_1, val_1_2, val_1_3, val_2_1, val_2_2, val_2_3,
    val_3_1, val_3_2, val_3_3, preview = FALSE)

Arguments

`val_1_1`	A hex value for cell 1-1
`val_1_2`	A hex value for cell 1-2
`val_1_3`	A hex value for cell 1-3
`val_2_1`	A hex value for cell 2-1
`val_2_2`	A hex value for cell 2-2
`val_2_3`	A hex value for cell 2-3
`val_3_1`	A hex value for cell 3-1
`val_3_2`	A hex value for cell 3-2
`val_3_3`	A hex value for cell 3-3
`preview`	A logical scalar; if `TRUE` (default), an image preview will be generated. If `FALSE`, a vector with hex color values will be returned.

Examples

custom_pal <- bi_pal_manual(val_1_1 = "#E8E8E8", val_1_2 = "#73AE80",
  val_2_1 = "#6C83B5", val_2_2 = "#2A5A5B")
