treeheatr: an introduction

vignette documentation github-action-status

Your decision tree may be cool, but what if I tell you you can make it hot?

Changes in treeheatr 0.2.0

The first argument of heat_tree(), data is now replaced with x, which can be a dataframe (or tibble), a party (or constparty) object specifying the precomputed tree, or partynode object specifying the customized tree. custom_tree argument is no longer needed.

Install

Please make sure your version of R >= 3.5.0 before installation.

You can install the released version of treeheatr from CRAN with:

install.packages('treeheatr')

Or the development version from GitHub with remotes:

# install.packages('remotes') # uncomment to install devtools
remotes::install_github('trang1618/treeheatr')

Examples

Penguin dataset

Classification of different types of penguin species.

library(treeheatr)

heat_tree(penguins, target_lab = 'species')

Wine recognition dataset

Classification of different cultivars of wine.

heat_tree(wine, target_lab = 'Type', target_lab_disp = 'Cultivar')

How to Use

treeheatr incorporates a heatmap at the terminal node of your decision tree. The basic building blocks to a treeheatr plot are (yes, you guessed it!) a decision tree and a heatmap.

Make sure to check out the vignette for detailed information on the usage of treeheatr.

Please open an issue for questions related to treeheatr usage, bug reports or general inquiries.
