These color ramp functions create color scales that can be used for making ggplot2 plots and gt tables. Color ramps are based on the palette_wjake color palette.
Usage
make_color_pal(colors, bias = 1)
ramp_blue(output, end = "#FFFFFF")
ramp_yellow(output, end = "#FFFFFF")
ramp_yelblu(output, mid = "#F0F0F0")
ramp_orgblu(output, mid = "#999999")Arguments
- colors
colors to interpolate; must be a valid argument to
col2rgb().- bias
a positive number. Higher values give more widely spaced colors at the high end.
- output
Colors to pull from the color ramp. Numbers range from 0-1, which is a normalized sliding scale of the color ramp.
- end
The end color that the base color should fade into.
- mid
For pre-made diverging palettes, the color of the midpoint of the scale.
Value
make_color_pal() returns a function that accepts a numeric vector
of values between 0 and 1 and returns a character vector of hex color
codes. ramp_blue(), ramp_yellow(), ramp_yelblu(), and ramp_orgblu()
return a character vector of hex color codes.
Details
make_color_pal() can be used to create a color ramp function for any set of
valid colors.
ramp_blue(), ramp_yellow(), and ramp_yelblu() are pre-made color ramps
based on the blue and yellow colors from the palette_wjake color palette.
ramp_orgblu() is a pre-made color ramp based on the first two colors from
the palette_okabeito color palette.
Examples
new_ramp <- make_color_pal(c("red", "grey", "blue"))
new_ramp(seq(0, 1, length.out = 10))
#> [1] "#FF0000" "#F02A2A" "#E25454" "#D37E7E" "#C5A8A8" "#A8A8C5" "#7E7ED3"
#> [8] "#5454E2" "#2A2AF0" "#0000FF"
# Pre-made palettes
ramp_blue(seq(0, 1, by = 0.2))
#> [1] "#FFFFFF" "#CCEBF0" "#99D8E2" "#65C5D3" "#32B2C5" "#009FB7"
ramp_yellow(seq(0.2, 1, length.out = 5))
#> [1] "#FEF7E0" "#FEEFC1" "#FEE7A3" "#FEDF84" "#FED766"
