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.
Calculates the Delaunay triangulation and the Dirichlet or Voronoi
tessellation (with respect to the entire plane) of a planar point set.
Plots triangulations and tessellations in various ways. Clips
tessellations to sub-windows. Calculates perimeters of tessellations.
The software hasn't been updated since 2002 and is probably full
of security problems. Two packages were using it. (gpsdrive has a
newer version in wip.)
17.5.14:
Update to iso-codes 3.75, which fixes 13389 again. (bad parent codes for GB).
Switch from building on drone.io (discontinued service) to bitbucket’s Pipelines.
Update pytest dependencies to get rid of API warnings.
17.01.08:
Update to iso-codes 3.73, which fixes 13389 (bad parent codes for CZ).
17.01.02:
Return empty lists from the subdivision database if the country exists but does not have any subdivisions. Fixes 13374.
Some typo fixes. Thanks to @VictorMireyev.
Update to iso-codes-3.72.
new packages. Most of which are the remaining modules of the Tryton
platform which weren't packaged. The others are dependencies of the new
modules. This was tested on FreeBSD and is based in large part on Richard
Palo's (richard@) work. This is the most recent release of the Tryton
platform, version 4.2. There's a very large list of changes from the 3.8
series we have in pkgsrc. If you're interested, those functional changes
can be found here:

GeoLite2 databases are free IP geolocation databases comparable to,
but less accurate than, MaxMind's GeoIP2 databases. GeoLite2
databases are updated on the first Tuesday of each month.
IP geolocation is inherently imprecise. Locations are often near the
center of the population. Any location provided by a GeoIP database
should not be used to identify a particular address or household.
Use the Accuracy Radius as an indication of geolocation accuracy for
the latitude and longitude coordinates we return for an IP address.
The actual location of the IP address is likely within the area
defined by this radius and the latitude and longitude coordinates.
These are presented as straight CSV files, and can be manipulated with standard
tools.
Note: this commit is part of reorganizing some of the recently
imported R packages, which are being reimported into more appropriate
categories (and removed from math) as a result of a recent discussion
on tech-pkg and privately with wiz@. See the thread starting with:
