fhir_columns-class

An object of class <code>fhir_columns</code> is part of a fhir_table_description
in a fhir_design and holds information on the elements
that should be extracted from the FHIR resources, as well as the column names of the resulting data.frame.
The elements to be extracted are indicated by XPath xpaths.

Useful tools for conveniently downloading FHIR resources in xml format
and converting them to R data.frames. The package uses FHIR-search to download bundles
from a FHIR server, provides functions to save and read xml-files containing such bundles
and allows flattening the bundles to data.frames using XPath expressions. FHIR® is the registered trademark
