makePalette

makePalette is a package containing functions that allow you to create your own color palette from an image, using mathematical algorithms.

Installation ⏬

Install makePalette from CRAN:

install.packages("makePalette")

Usage 💪

library(makePalette)

You need an image in jpg, png, tiff or similar format, stored in the hard disk of your PC or in some url.

Examples with the makePaletteCLARA function (Clustering Large Applications)

Example 1

url1 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture01.jpeg"
curl::curl_download(url1, "picture01.jpeg")
colors <- makePaletteCLARA("picture01.jpeg")
barplot(1:length(colors), col=colors)

By default, the function will return a palette of 4 colors.

If you want a palette with more colors, just specify it in the n parameter.

colors <- makePaletteCLARA("picture01.jpeg", n = 10)
barplot(1:length(colors), col=colors)

Example 2

url3 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture03.jpeg"
curl::curl_download(url3, "picture03.jpeg")
colors <- makePaletteCLARA("picture03.jpeg", n = 6)
barplot(1:length(colors), col=colors)

Example 3

url5 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture05.png"
curl::curl_download(url5, "picture05.png")
colors <- makePaletteCLARA("picture05.png", n = 6)
barplot(1:length(colors), col=colors)

Example 4

url6 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture06.png"
curl::curl_download(url6, "picture06.png")
colors <- makePaletteCLARA("picture06.png", n = 6)
barplot(1:length(colors), col=colors)

Examples with the makePaletteKM function (k-Means)

Example 5

url2 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture02.jpg"
curl::curl_download(url2, "picture02.jpg")
colors <- makePaletteKM("picture02.jpg", n = 10)
barplot(1:length(colors), col=colors)

Example 6

url4 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture04.tiff"
curl::curl_download(url4, "picture04.tiff")
colors <- makePaletteKM("picture04.tiff", n = 6)
barplot(1:length(colors), col=colors)

Example 7

url6 = "https://github.com/musajajorge/makePalette/raw/main/imgs/picture06.png"
curl::curl_download(url6, "picture06.png")
colors <- makePaletteKM("picture06.png", n = 6)
barplot(1:length(colors), col=colors)
