jpmesh 2.1.0.9000

jpmesh 2.1.0 (2022-01-10)

• Reviewed the handling of meshcode in the data.frame #59. Added .keep_class to the argument of the function to be returned as a data.frame (FALSE by default), and changed it so that the user can select the class.
• Changed the method of generating mesh polygons smaller than 1km.

jpmesh 2.0.2 (2021-06-25)

• Following sf updates

jpmesh 2.0.1 (2021-01-13)

• Fix vdiffr conditionally

jpmesh 2.0.0 (2020-11-26)

• To introduced a new meshcode class. This is one of the classes of S3. The mesh code values returned by the package are implemented in the meshcode class. Also, meshcode() creates an object of meshcode class of arbitrary size #49.
  • is_meshcode(), as_meshcode()
• Update administration mesh code data using at administration_mesh()
• Activate a memoise some functions for efficiency #50.
• Support 100m mesh code as subdiv_meshcode class #51.

jpmesh 1.2.1 (2020-05-06)

• Meshcode evaluation is now more stringent.
  • Fixed a problem where a non-existent mesh code would return an incorrect value when given as input (#45).

jpmesh 1.2.0 (2020-03-26)

• API changes to functions that take mesh_size (#35). It has been changed to a numeric value in km unit instead of the mesh size string.

coords_to_mesh(141.3468, 43.06462, mesh_size = "10km")

to

coords_to_mesh(141.3468, 43.06462, mesh_size = 10)

• Add mesh_convert() that mesh size can be changed freely.

# Scale up
mesh_convert("52350432", 80)
# Scale down
mesh_convert("52350432", 0.500)

• meshcode_sf() export data.frame to sf which include meshcode variable.

Improvement

• Add image test with vdiffr (#41).
• Introducing GitHub actions.

• Set sf object espg as 4326.

New features

• is_meshcode(), is_corner()... Predict meshcode format and positions for utility and certain.
• rmesh()... Generate random sample meshcode.
• Rename find_neighbor_mesh() to neighbor_mesh() and separate features (not export functions).

• Modified eval_jp_boundary() that internal function.
  • Add ... parameters to pass additional arguments.
  • Improved problem of giving mesh code outside of Japan (reopen #6).
• fine_separate()... Correct behavior when entering 1 km meshcode (#9).

jpmesh 1.0.0 (2017-11-26)

• Consolidation of functions by integration and abolition. Rename of function name. Such as, argument order.
• You can now convert coordinates to 125m meshcode. As a result, it became to support to all meshcodes.
