An Exploration in R

About the Book

Hardcover version available on Amazon.

Bio/Recursion introduces topics in programming, computer science, and bioinformatics via examples in the R programming language. While often associated with statistics, Bio/Recursion employs R’s algorithmic capabilities to implement and visualize several fascinating methods, ranging from DNA alignment to drawing fractal trees.

Recursion (self-reference) provides a central theme, with topics spanning searching, sorting, data structures, proofs, fractals, and important bioinformatics algorithms.
