XRPython - An Interface from R to Python

This package provides an interface from R to Python, based on the XR structure, as implemented in the XR package, in this repository.

The interface is designed as a basis for computations in R that use functions, objects and classes in Python. In particular, the design caters to programmers developing application packages. The XR structure encourages definition of proxy functions and classes in \R{}, which users of the package can treat essentially as they would in R, without special programming imposed by the interface.

The interface structure is described in the book Extending R (John M. Chambers, 2016, Chapman & Hall). A pdf version of the XRPython chapter from the book is included with the documentation of this package. To open the pdf file from R:

RShowDoc("Chapter_XRPython", package = "XRPython")

As of version 0.8, the package uses package 'reticulate' for its low-level interface to Python, replacing 'rpython'.

To test whether a working Python interface can be opened on this machine: okPython(TRUE) which will return TRUE or FALSE and report the cause of a failure.
