Overview

About

Maintained by Jon ClaydenCRAN page ↗GitHub ↗Issues ↗

Functions for easily manipulating colours, creating colour scales and calculating colour distances.

Changes in 1.5.0

Names and dimnames are now supported for shade objects and can be set using the usual accessor functions. Names are initialised from standard colours where these are specified rather than a hex code, propagated through operations like concatenation and shown by swatch() as labels on each box. Dimnames are set automatically when a matrix is created by updating colour properties on a vector, and are shown by swatch() as axis labels.
The new shades() convenience function is a variant of shade() that combines construction of shade objects with concatenation. It supports inline colour naming using standard argument names, and creating shade objects from source objects of different types.
New colour property accessor function luminance() has been added, as has the contrast() function for (W3C) colour contrast.

There is now full support for the Oklab colour space.
Empty shade vectors are now allowed and can be created with shade().
The swatch() function gains extra parameters for controlling additional aspects of the plot.
The argument to function objects created by gradient() is now called n rather than steps, for compatibility with tinyplot.
The tinytest package is now used for testing.
The README now includes an example of using shades with tinyplot, as well as ggplot2.
A small roxygen issue has been fixed (#9).

From NEWS in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("shades", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("jonclayden/shades")

Development version from jonclayden/shades. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-shades

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-shades

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-shades

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
