Get vector of colors for observations in one column of a data frame

Assigns one color per unique observed value in dat[[colname]], drawn from palette starting at color_offset. If the palette is too short, falls back to get_random_colors(). Factor columns use factor-level order; other columns use first-observed order.

Usage

get_colors_vctr(dat, colname, palette = mosuite_palette, color_offset = 0L)

Arguments

dat

data frame

colname

column name in dat

palette

Character vector of colors to assign. Defaults to mosuite_palette.

color_offset

integer; number of palette colors to skip before assigning colors to this column's values. Used by get_colors_lst() to avoid repeating colors across columns with few unique values.

Value

Named character vector of hex colors, one per unique observed value in dat[[colname]].

Examples

get_colors_vctr(nidap_sample_metadata, "Group")
#>         A         B         C 
#> "#5954d6" "#e1562c" "#b80058" 
get_colors_vctr(nidap_sample_metadata, "Group", color_offset = 3L)
#>         A         B         C 
#> "#00c6f8" "#d163e6" "#00a76c"
