The previous version of the transpiler converted R syntax for loops, conditionals, array access, and functions etc. to Fortran, but R also has a lot of built-in statistical and linear algebra algorithms, which are now in a module, documented [here](https://github.com/Beliavsky/R-to-Fortran/blob/main/xr2f_runtime_api.md), that the transpiler or stand-alone Fortran programs can use. There are procedures for - Printing Arrays - Vectors, Sequences, and Repetition - Matrices and Array Semantics - Set, Match, and Index Helpers - Random Numbers and Sampling for Many Distributions - Probability and Special Functions - Summary Statistics and Linear Algebra - Data Frames, Tables, and Grouped Operations - Model and Test Result Types (the result of a statistical analysis is returned in a derived type) - Optimization and Integration - Smoothers and Time-Series Analysis - Clustering - Dates, Files, and Strings
