Flametree provides a system for making generative art in R, written with two goals in mind. First, and perhaps foremost, art is inherently enjoyable and generative artists working in R need packages no less than any other R users. Second, the system is designed to be useful in the classroom: getting students to make artwork in class is an enjoyable exercise and flametree can be used as a method to introduce some key R concepts in a fun way. The package is not (yet) on CRAN but you can install the development version of flametree with:
# install.packages("devtools") devtools::install_github("djnavarro/flametree")
Flametree is fairly flexible and produces art in several different styles. One example is shown here, other possibilities are described throughout the documentation.
