jwst

The goal of jwst is to be an R color palette inspired by the beautiful images from the James Webb Space Telescope (JWST).

More on the JWST itself here https://jwst.nasa.gov/index.html.

Installation

You can install the development version of jwst like so:

remotes::install_github("erictleung/jwst")

Example

This is a basic example which shows you how to solve a common problem:

library(jwst)

names(jwst_palettes)
#> [1] "carina"            "smacs"             "southern_nebula_1"
#> [4] "southern_nebula_2" "stephans_quintet"

You can call the palette in just one command.

jwst("carina")

If you want a specific number of colors, you can also do that.

jwst("carina", 3)

jwst("smacs")

jwst("southern_nebula_1")

jwst("southern_nebula_2")

jwst("stephans_quintet")

Generating your own

If you don’t like the color here, you can experiment and make your own!

library(imgpalr)
#> Warning: package 'imgpalr' was built under R version 4.1.3

set.seed(1)

(x <- paste0(system.file(package = "jwst"), "/help/figures/carina.jpg"))
#> [1] "C:/Users/leune006/R/win-library/4.1/jwst/help/figures/carina.jpg"

image_pal(
  x[1],
  type = "div",
  saturation = c(0.75, 1),
  brightness = c(0.75, 1),
  plot = TRUE
)

#> [1] "#A95F34" "#BE8766" "#D3AF99" "#E9D7CC" "#FFFFFF" "#C9D9EA" "#93B3D5"
#> [8] "#5E8DC0" "#2968AC"

List other images available.

list.files(paste0(system.file(package = "jwst"), "/help/figures"))
#>  [1] "carina.jpg"
