How To Install root-r on CentOS 8
Introduction
In this tutorial we learn how to install root-r on CentOS 8.
What is root-r
ROOT R is an interface in ROOT to call R functions using an R C++ interface. This interface opens the possibility in ROOT to use the very large set of mathematical and statistical tools provided by R. With ROOT R you can perform a conversion from ROOT’s C++ objects to R’s objects, transform the returned R objects into ROOT’s C++ objects, then the R functionality can be used directly for statistical studies in ROOT.
We can use yum or dnf to install root-r on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install root-r.
