New Extension Command: STATS PACKAGE INSTALL

[jkpeck]

The STATS PACKAGE INSTALL extension command  installs Python or R modules needed by a begin program block or an extension command whose install did not include them.  This will make using an extension easier than the current means when there are external dependencies such as for the STATS TEXTANALYSIS extension.

It Installs packages from PyPI (Python) or CRAN (R).  It does not install items from the Extension Hub.  I have found that it is not uncommon for CRAN packages not to list all their dependencies.  

This extension requires Statistics V27 or later.  On some systems, it will require starting Statistics in administrator mode.

STATS PACKAGE INSTALL is available on the Extension Hub.
