With GraalVm you can execute R scripts directly from Java without any conversion, microservices, or endpoints. We already have seen an example in Python, let’s see how to do it in R.

How to use Python with Quarkus and GraalVM

Quarkus is not just a backend framework. Rather, it’s a platform or ecosystem. With Quarkus you can write as JavaEE, as well as Spring applications, and even mix them, without thinking of underlying details.

Calling code from different languages can be beneficial in terms of saving lots of hours, firstly of course because you don’t need to re-write code from one language to another, that can lead to potential bugs, and second thing is that you don’t need to rewrite anything from start.
