RGPR — An open-source package to process and visualize GPR data

RGPR, the first ground-penetrating radar (GPR) data processing package written in the R language, is presented. R is a free and open-source high-level programming language for statistical computing. RGPR is built around two main classes to process and visualize GPR data as well as to keep track of the processing steps. Although RGPR is still a work in progress, many of the basic processing methods are already implemented. The package is hosted on GitHub for collaborative development and is easily expandable. Through its openness and the rich R environment, RGPR promotes reproducible GPR research as well as GPR processing learning.
