class RRgeos(RPackage):
"""Interface to Geometry Engine - Open Source ('GEOS').
Interface to Geometry Engine - Open Source ('GEOS') using the C 'API' for
topology operations on geometries. The 'GEOS' library is external to the
package, and, when installing the package from source, must be correctly
installed first. Windows and Mac Intel OS X binaries are provided on
'CRAN'. ('rgeos' >= 0.5-1): Up to and including 'GEOS' 3.7.1, topological
operations succeeded with some invalid geometries for which the same
operations fail from and including 'GEOS' 3.7.2. The 'checkValidity='
argument defaults and structure have been changed, from default FALSE to
integer default '0L' for 'GEOS' < 3.7.2 (no check), '1L' 'GEOS' >= 3.7.2
(check and warn). A value of '2L' is also provided that may be used,
assigned globally using 'set_RGEOS_CheckValidity(2L)', or locally using the
'checkValidity=2L' argument, to attempt zero-width buffer repair if invalid
geometries are found. The previous default (FALSE, now '0L') is fastest and
used for 'GEOS' < 3.7.2, but will not warn users of possible problems
before the failure of topological operations that previously succeeded.
From 'GEOS' 3.8.0, repair of geometries may also be attempted using
'gMakeValid()', which may, however, return a collection of geometries of
different types."""
