Overview

About

Maintained by Thomas Lin PedersenCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

Graphical scales map data to aesthetics, and provide methods for automatically determining breaks and labels for axes and legends.

Changes in 1.4.0

Range training now supports custom classes. Continuous classes require a range() method that returns numeric values. Discrete classes require a levels() method (and optionally a droplevels() method) (#480).
New label_glue() labelling function for interpolated strings (#457).
fullseq() and by extension breaks_width() can now deal with unsorted ranges (#435).
New label_date_short(leading) argument to replace leading zeroes (#442)
breaks_pretty() will return the input limit when it has no range (#446)
breaks_exp() now provides more sensible breaks for the exponential transform
transform_exp() now has more sensible breaks, available in breaks_exp() (@teunbrand, #405).
The scales package now keeps track of known palettes. These can be retrieved using get_palette() or registered using set_palette() (#396).

Show all changes in 1.4.0Hide the rest of the changes in 1.4.0

label_log() has a signed argument for displaying negative numbers (@teunbrand, #421).
New label_dictionary() for named lookup of labels (#458).
New function compose_label() to chain together label formatting functions (#462)
Palette function now have classes, attributes and coercion methods (@teunbrand, #426).
Added colour manipulation functions: col_shift(), col_saturate(), col_darker(), col_lighter() and col_mix() (@teunbrand, #423)
label_date_short() gains tz and locale argument (#478)

From NEWS.md in the release

Install

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

install.packages("scales", 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("r-lib/scales")

Development version from r-lib/scales. 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-scales

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-scales

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-scales

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.
