Is Statistics::Descriptive similar to using Statistics::R module( in a PERL Script)?

Question

I think Statistics::Descriptive does not call R language module, whereas the Statistics::R does.

Am I right?

Answer 1

Statistics::Descriptive is a simple pure-Perl module offering basic functionality for stats. You can read the documentation or the source code to answer the question yourself: Statistics::Descriptive does not use R under the hood. Who would have thought that you could do statistical ananlysis with languages other than R?

The Statistics::Descriptive and Statistics::R modules are very different: Whereas S::D offers Perl objects representing data collections which you can call various methods on, the S::R is just a convenient wrapper around an R REPL, and requires you to write snippets of R code.
