Value

A Van Gogh color palette generator.
Description
These are some color palettes from a selection of Vincent van Gogh's paintings.
Usage
vangogh_palette(name, n, type = c("discrete", "continuous"))
Arguments
name |
Name of desired palette. Choices are:
|
n |
Number of colors desired. All palettes have a standard of 5 colors. If omitted, uses all colors. |
type |
Either "continuous" or "discrete". Use "continuous" to automatically interpolate between colours. @importFrom graphics rgb rect par image text |
Value
A vector of colors.
Examples
vangogh_palette("StarryNight")
vangogh_palette("SelfPortrait")
vangogh_palette("Cypresses")
vangogh_palette("Cypresses", 3)
# If you want a continous paletted based on the colors already found in the preset
# palettes, you can interpolate between existing colours accordingly.
pal <- vangogh_palette(21, name = "StarryRhone", type = "continuous")
Complete list of palettes:
Description
Use vangogh_palette to construct palettes of desired length.
Usage
vangogh_palettes
Format
An object of class list of length 15.
Show a single palette
Description
Display a single palette to see whether it meets your needs.
If no num parameter is given,
all the colours in the palette will be displayed.
If num is less than the number of colours in the palette,
then only the first num colours will be displayed.
If num is greater than the number of colours in the palette,
then that many colours will be generated by linear interpolation
over the vector of colours in the chosen palette.
Usage
viz_palette(pal, ttl = deparse(substitute(pal)), num = length(pal))
Arguments
pal |
character, vector of (hexadecimal) colours representing a palette |
ttl |
character, title to be displayed (the name of the palette) |
num |
numeric, the number of colours to display |
Value
A vector of colors from a single palette
Examples
viz_palette(vangogh_palettes$StarryNight)
viz_palette(vangogh_palettes$StarryNight, "StarryNight")
viz_palette(vangogh_palettes$StarryNight, "StarryNight first 4", num = 4)
viz_palette(vangogh_palettes$StarryNight, "StarryNight interpolated to 25", num = 25)
