Inspect the usage section in an Rd object.
inspect_usage(rdo)
a list of comparison results as described in `Details' (todo: give more details here)
an Rd object.
Georgi N. Boshnakov
The usage section in the Rd object, rdo
, is extracted and
parsed. The usage of each function described in rdo
is
obtained also from the actual installed function and compared to the
one from rdo
.
The return value is a list, with one element for each function usage
as returned by compare_usage1
.
One of the consequences of this is that an easy way to add a usage
description of a function, say fu
to an existing Rd file is to
simply add a line fu()
to the usage section of that file and
run reprompt
on it.
