sfhotspot 0.8.0
- All functions can now handle SF objects in which the geometry column
has a name other than
geometry (#30).
hotspot_kde() progress bar is now suppressed by
quiet = TRUE (#25).- When KDE bandwidth is selected automatically based on a rule of
thumb, the reported bandwidth now takes into account the value of
bandwidth_adjust (#32).
sfhotspot 0.7.1
- Added warning if automatically created grids contain more than
100,000 cells, since this can cause other functions in the package to
run very slowly (#24).
- Fixed bug in which cell size could be incorrectly rounded to zero
(#26).
- Removed
covr dependency.
sfhotspot 0.7.0
- New function
hotspot_change() and corresponding methods
for autoplot() and autolayer() for measuring
change in the frequency of events between two time periods (#14).
sfhotspot 0.6.1
- Fixed bug in which the message produced when setting bandwidth
automatically referred to the unadjusted rather than adjusted bandwidth
(#22).
sfhotspot 0.6.0
- New function
hotspot_dual_kde() for estimating
different relations between the density of two point layers (#1).
- New dataset
memphis_population showing the 2020
population of the centroids of census blocks in Memphis, TN.
sfhotspot 0.5.0
- Users can now specify weights for counts of points and kernel
density estimation via the
weights argument to
hotspot_count(), hotspot_kde() and
hotspot_gistar().
sfhotspot 0.4.0
- Users can now provide their own grid using the
grid
argument to the hotspot_*() family of functions.
- New function
hotspot_grid() added so users can create a
rectangular or hexagonal grid separately from counting points,
calculating KDE values, etc. This may be useful to use the same grid for
different datasets covering a similar area.
sfhotspot 0.3.1
- Fixed bug where
... arguments were not passed on to
SpatialKDE::kde() as specified in the documentation.
sfhotspot 0.3.0
- Added
autoplot() methods for plotting the results
produced by hotspot_count(), hotspot_kde() and
hotspot_classify().
- Added
bandwidth_adjust argument to
hotspot_kde() and hotspot_gistar() so that
bandwidth can be set relative to the default.
sfhotspot 0.2.2
- Added checking for empty geometries and co-ordinates on Null Island
(or equivalent zero co-ordinates in other co-ordinate systems). Empty
geometries produce an error and zero co-ordinates produce a
warning.
sfhotspot 0.2.1
- Fixed a bug where a grid of cells could not be created for an SF
object with no CRS defined (and improved the error message when trying
to calculate KDE values in this circumstance).
- Fixed a bug where the grid returned by the
hotspot_*()
family of functions was not clipped to the convex hull of the data, as
specified in the documentation.
sfhotspot 0.2.0
- Added
hotspot_classify() and
hotspot_classify_params() functions.
- Added references to function documentation pages and the DESCRIPTION
file.
- Changed
\dontrun{} in some of the documentation
examples to \donttest{}.
sfhotspot 0.1.1
- Fixed a problem with some of the examples in the documentation
taking too long to run, which caused them to fail CRAN checks.
sfhotspot 0.1.0
- Initial release of the package with the functions
hotspot_count(), hotspot_kde() and
hotspot_gistar().
