Version 0.1.2 • sfdep

library(sfdep)

While not too far from the initial CRAN release of sfdep, this release represents a some rather sizeable changes to the package.

This can be broken down into three categories:

Colocation Analysis

This is extremely exciting as this is the first open source implementation of Colocation Quotients that I am aware of.

This is a very big addition to sfdep.

spacetime(), new_spacetime(), validate_spacetime():
- Creating spacetime objects
activate(), active():
- changing spacetime context and determining active context
as_sf(), as_spacetime():
- casting between spacetime and sf objects
is_spacetime():
- determine if an object is a spacetime object
is_spacetime_cube():
- determine if a spacetime object is a spatio-temporal full grid aka spacetime cube
complete_spacetime_cube():
- if a spatio-temporal sparse grid, add rows to make a spatio-temporal full grid (spacetime cube)
set_col(), set_nbs(), set_wts():
- add columns from geometry contexst to data context
emerging_hotspot_analysis():
- conduct emerging hotspot analysis
spt_update():
- update times and locations attributes of a spacetime object

Fixes a bug in local_g_perm() and local_gstar_perm() which would return the G value before being converted into a z-score
