-This function is useful when adding :class:`data.frames` objects to a Scenario:

-      Ensure the the R version installed is either 32- *or* 64-bit (and >= 3.5.0), consistently with GAMS and Java.
-      Having both 32- and 64-bit versions of R, or mixed 32- and 64-bit versions of different packages, can cause errors.

-   Type the following commands to build, then install, ``rixmp`` and its dependencies, including reticulate_::
-
-    $ R CMD build rixmp
