In parttree: Visualize Simple 2-D Decision Tree Partitions

parttree 0.1.0

Our first CRAN submission. 🎉🎉

Breaking changes

• Move ggplot2 to Enhances, following the addition of a dedicated (base R) plot.parttree method. The geom_parttree() function is still available, but requires that ggplot2 is already been installed on the user's system. (#18)
• The flipaxes argument has been renamed to flip, e.g. parttree(..., flip = TRUE). (#18)

Improvements

• Parttree objects now have their own class with a dedicated plot.parttree method, powered by tinyplot. (#18)
• Major speed-up for extracting parttree nodes and coordinates on complicated trees. (#15)
• Add method for tidymodels workflows objects fitted with "rpart" engine. (#7 by @juliasilge).

Bug fixes

• Support for negative values. (#6 by @pjgeens)
• Better handling of single-level factors and flip(axes). (#5)
• Handling of complex formula expressions. (#17)

Internals

• Several dependency adjustments, e.g. tinyplot to Imports and ggplot2 to Suggests. (#18)
• Added SVG snapshots for image-based tests. (#18)
• Bump ggplot2 version dependency to match deprecated functions from 3.4.0.
• Switched to "main" as primary GitHub branch for development.
• Added two dedicated vignettes.

parttree 0.0.1

• Create parttree() generic. (again, #3 by @zeileis)
• Support for partykit objects (i.e. constparty class), which in turn allows support for base plot methods. (#3 by @zeileis)
• ggplot2 moves from imports to depends and is now automatically loaded with parttree.
• Add flipaxes argument for easy switching in case or mismatch plot orientation. (#2 by @brhkim)
• Added a NEWS.md file to track changes to the package.

parttree 0.0.0.9000

• Initial set of functions.
