ggsci 4.1.0

CRAN release: 2025-10-25

Improvements

• Synchronize the iTerm color palettes with upstream (#72).

  This update adds 8 new palettes to iterm_palettes(): Hot Dog Stand variations, Matte Black, Poimandres variations, and Selenized Black. These palettes are now usable by pal_iterm(), scale_color_iterm(), and scale_fill_iterm().

  Additionally, the color values for 40+ existing iTerm palettes have been updated to match the latest upstream color specifications.

Documentation

• Add the ggsci iterm palettes microsite link to vignette("ggsci") (#70). This microsite helps users preview all iTerm color palettes available in ggsci.

ggsci 4.0.0

CRAN release: 2025-09-23

New features

• Add the Primer design system (from GitHub) palette in scale_color_primer() and scale_fill_primer() (#62, #63).
• Add the Atlassian Design System palette in scale_color_atlassian() and scale_fill_atlassian() (#64).
• Add 400+ iTerm palettes in scale_color_iterm() and scale_fill_iterm() (#67).

Improvements

• Add example_scatterplot() and example_barplot() to simplify discrete scale examples in documentation. This reduces boilerplate code and makes it easier to maintain the examples. Also improves graphical appearance of the examples by using a minimalist theme with alternative data subsets (#61).

Maintenance

• Refactor the logo generation script from an R script to a shell script and move it into tools/ (#66).
• Use standard static imports workflow (#58).

ggsci 3.2.0

CRAN release: 2024-06-17

New features

• Add the Observable 10 palette in scale_color_observable() and scale_fill_observable() (#41).
• Add Bootstrap 5 color palettes (continuous) in scale_color_bs5() and scale_fill_bs5() (#18).
• Add Tailwind CSS color palettes (continuous) in scale_color_tw3() and scale_fill_tw3() (#19).

Improvements

• Move internal color palette data from R/sysdata.rda to R/palettes.R. This change enhances package development transparency, reduces unnecessary indirection, and simplifies contributions by avoiding the construction of the palette data using the R script in data-raw/ (#42).
• For continuous palette examples, remove the reshape2 dependency and use more compact grid layout to reduce output image size (#45).

ggsci 3.1.0

CRAN release: 2024-05-21

New features

• The BMJ color palettes are implemented in scale_color_bmj() and scale_fill_bmj() (thanks, @huichen99, #32).

Documentation

• Convert Rd syntax to Markdown in roxygen2 documentation. This simplifies documentation formatting and makes it much easier to add new color scales for contributors (#35).

ggsci 3.0.3

CRAN release: 2024-03-25

Improvements

• Detect ggplot2 version at runtime to determine if the argument scale_name is needed for all discrete_scale() calls. This ensures ggsci always works regardless of the ggplot2 version installed (thanks, @flyingicedragon, #29).

ggsci 3.0.2

CRAN release: 2024-03-18

Improvements

• Remove scale_name from all discrete_scale() calls because the argument has been deprecated in ggplot2 3.5.0 (thanks, @DanChaltiel, #25).

ggsci 3.0.1

CRAN release: 2024-03-02

Improvements

• Expand the FAQ vignette to include a solution for customizing color selection and ordering in a palette with self-defined color scale functions (#23).
• Fix “lost braces” check notes on r-devel by using Unicode characters (nanxstats/ggsci@a91faf1).

ggsci 3.0.0

CRAN release: 2023-03-08

New features

• Added three Flat UI color palettes in
  • scale_color_flatui()
  • scale_fill_flatui()
  and one color palette inspired by the logo of frontiers.org in
  • scale_color_frontiers()
  • scale_fill_frontiers() (thanks, @clarajegousse, #14).
• Added three COSMIC color palettes in
  • scale_color_cosmic()
  • scale_fill_cosmic()
  (thanks, @jhrcook, #5, #7).

Improvements

• Use a proper, three-component version number following Semantic Versioning.
• Reduce output figure size in vignettes and README.Rmd by switching to the ragg PNG device and using pngquant for compression.
• Added a new vignette on frequently asked questions.
  • A simple solution to interpolate the color palettes when the data has more categories than the number of colors in a discrete color scale.
  • A note on using a color scale consistently for multiple ggplot2 plots by setting global options (thanks, @DanChaltiel, #13).
• Replace size with linewidth in code examples for ggplot2 >= 3.4.0.
• Replaced the previous logo with a new hex sticker logo.
• Replaced previous CI/CD solutions with GitHub Actions workflows.
• Fixed broken or moved links in function documentation and vignettes.
• Removed the LazyData field from DESCRIPTION.
