get_cell_vertex(), get_cell_vertexes(), and
vertex_to_point() are available for interacting with H3 in
vertex mode.

cell_area, edge_length,
get_dist, and get_res0.
- Revised internal function
prep_for_pt2h3
Version 1.1.3
Version 1.1.2

issues
- Move to Github Actions for CI workflow
- Remove unneeded lwgeom dependency
- Bugfix for accessing
h3_info_table when library not
loaded explicitly
Version 1.1.1
- Updated to h3-js 3.6.2 - expect improvements to
polyfill() behaviour
Version 1.1
- Updated to h3-js 3.6.1
- Added
get_centerchild(), which will return the central
child of a hexagon at a given resolution.
- Added
get_pentagons(), which will return the twelve
pentagon indexes at a given resolution.
Version 1.0
- Updated to h3-js 3.5.0, now using official browser bundle
- Added
get_faces(), which returns the icosahedron
face(s) for a given H3 address.
Version 0.9
- Updated to h3-js 3.4.2
- Replaced custom function
min_path() with official
version grid_path(), which wraps h3Line to
find a path between two addresses.
- Added custom function
h3_to_line(), which converts a
vector of H3 addresses to sfc_LINESTRING.
Version 0.8
- Updated to h3-js 3.3.0 and babel-polyfill 6.26.0
Version 0.7
- Removed
nearest_neighbour(), its fundamentally
flawed.
- Simplified output of
get_local_ij() to a matrix when
simple = TRUE
- Improved outputs from
h3_to_point()
- Efficiency improvements to
h3_to_point() and
polyfill()
h3_to_point(), h3_to_polygon(), and
polyfill() now take a wider range of input objects.
Version 0.6
- Update core library to v 3.2.0
- Add
get_local_ij() and get_local_h3(),
wrapping the experimental local coordinate system functions
h3.experimentalH3ToLocalIj and
h3.experimentalLocalIjToH3 respectively.
Version 0.5.1
- Added custom function
min_path() to find a
minimum-steps path between two H3 addresses of the same resolution.
- Added custom function
nearest_neighbour() to find the
nearest neighbour for a given set of points. Use with caution, read the
notes.
Version 0.5.0
- change to v8 session handling (speed enhancement)
Version 0.4.5
- update core library to v 3.1.1
Version 0.4.4
- bugfix for
polyfill(). Where input sf
object only has a geometry column, a column called ‘ID_H3’ containing a
sequential ID field is now added before sending the geometry to the V8
session.
Version 0.4.3
- Update h3-js to release 3.1.0 -
https://github.com/uber/h3-js/releases/tag/v3.1.0
- Add
grid_distance(), which returns the number of
‘steps’ required to get from one H3 address to another (within the same
resolution).
Version 0.4.2
- Update h3-js to release 3.0.2 -
https://github.com/uber/h3-js/releases/tag/v3.0.2
Version 0.4.1
- Warnings converted to messages
- Multipolygon support for
h3_polyfill(), plus a message
when output resolution is way smaller than input extent.
Version 0.4.0
- Naming things is hard, but its vignette time so, y’know, now or
never. Function names are shorter now and make more sense.
- Added another info utility
res_cendist() for getting
the average distance between the center of each region represented by a
H3 address at a given resolution.
- Vignette covering core functionality added.
Version 0.3.1
- Reworked
to_point() to return an sfc_POINT
object, or an sf point data frame where
simple = FALSE.
- Improved outputs of
to_polygon() to have a similar
structure to h3_to_geo().
Version 0.3.0
- Reworked
point_to_h3() to take in an sf
point object and return the same when simple = FALSE,
resulting in a new dependency on tidyr. On the upside, one
can now request addresses for multiple resolutions at multiple points,
if one wishes to test the limits of one’s system.
Version 0.2.3
- Added public informational utilities
res_area(),
res_edgelen(), and res_count()
- Added data table of h3 address info for fast retrieval of
information using the above functions
- Fixed resolution validation bug, level 0 is now allowed
Version 0.2.2
- All unidirectional algorithms added:
are_neighbours(),
get_udedge(), is_valid_edge(),
get_udorigin(), get_uddest(),
get_udends(), get_udedges(), and
udedge_to_line().
Version 0.2.1
polyfill() and set_to_multipolygon()
added; new dependencies on sfand geojsonsf
have resulted.to_polygon() now returns an object with sf
geometry.compact() and uncompact() added, all
public core algorithms now available.
Version 0.1.3
- Simplified default output behaviour
get_parent(), get_children(),
get_kring(), get_kring_list(), and
get_ring() added.
Version 0.1.2
- Added remaining core functions
is_valid(),
is_pentagon(), is_rc3(),
get_base_cell(), get_res(), and
to_polygon().
- unit tests on all core functions.
Version 0.1.1
to_point() added.point_to_h3() bugfix. A pox on devs who think y,x is
ok.- NEWS and README added.
Version 0.1.0
point_to_h3() - first function implemented.
