Replaced lwgeom::st_perimeter() by
sf::st_perimeter() (available in version 1.0.15). The
package lwgeom is now under Suggests field
(fix #33).
fsr 2.0.0
Major changes
Defined a new hierarchical structure for defining the spatial
plateau data types:
Added two new spatial plateau data types: pcollection
and pcomposition.
Redefined the class named pgeometry.
Defined three spatial plateau data types that are subclasses of
pgeometry: ppoint, pline, and
pregion.
Specified validity methods for all classes according to the rules of
the Spatial Plateau Algebra.
These modifications are based on the pull requests performed by
Pedro V. A. B. de Venâncio, who is added as a contributor of the package
fsr in the current version (#26 - @pedbrgs and #27 - @pedbrgs).
Added spa_get_type() (based on the pull request #27 - @pedbrgs).
Updated and improved functions that create pgeometry
objects: create_pgeometry() and
create_empty_pgeometry() (#27 - @pedbrgs).
Improved the creation of components by redesigning
create_component(). component_from_sfg() is
deprecated (it will be removed in the next version of the package).
Enhanced fsr_plot() and added the support for
pcollection and pcomposition objects.
Added two new external functions that handle
pcollection objects: spa_flatten() and
pcollection_to_pcomposition() (based on the pull request #31 - @pedbrgs). They are
also used by fuzzy geometric set operations on pcollection
objects.
Enhanced fuzzy geometric set operations, which can now handle
different data types as input (based on the pull request #31 - @pedbrgs).
Deprecated spa_common_points() - use
spa_intersection() to get the common points of two plateau
line objects.
Deprecated spa_boundary_pregion() - use
spa_boundary to get the boundary of a spatial plateau
object.
Enhanced general operations (e.g., spa_core(),
spa_boundary()) to deal with the new spatial plateau data
types (based on the pull request #31 - @pedbrgs).
Added three new general operations: spa_alpha_cut(),
spa_strict_alpha_cut(), and spa_range().
Removed the dependency of packages FuzzyR and
utils.
Minor changes
Better organization of the source code by creating more R scripts
and rearranging the functions and classes in them.
Updated format.pgeometry() to include a parameter that
determines the maximum number of characters that are shown.
Updated spa_pwkt() to deal with the new classes (based
on the pull request #26 - @pedbrgs).
Updated spa_is_empty() to deal with the new classes
(based on the pull request #26 - @pedbrgs).
Updated as_tibble() to deal with the new classes.
Extended fuzzy numerical operations to deal with the new classes
(based on the pull request #30 - @pedbrgs).
Updated fuzzy topological relationships due to the changes in other
operators (based on the pull request #31 - @pedbrgs).
Minor changes in functions of the construction module to use
improved operations when manipulating spatial plateau objects.
Change in the list of
authors
Added Pedro Vinícius Almeida Borges de Venâncio (@pedbrgs) as a contributor
to the fsr.
We are grateful for the contributions of Felippe Galdino (@ocfgaldino) and Juliana
Strieder Philippsen (@JulianaStrieder) in the first
version of the package (1.0.0, 1.0.1, and 1.0.2). Their participation in
the package was concluded; thus, they were removed from the list of
authors in this version of the package, which includes several changes,
improvements, and new methods.
fsr 1.0.2
Minor changes
Added the parameter d_tolerance in the
spa_creator() function. This parameter is employed by the
package sf when computing the Voronoi diagram and Delaunay
triangulation in the corresponding construction policies.
Bug fixes
Fixed the fuzzy numerical operations when dealing with empty
objects.
Fixed spa_core() to return an empty crisp spatial
object when the input has not a core.
Fixed some if statements and calculations in the fuzzy topological
relationships.
Fixed the clipping operation in spa_creator() when
using the construction policies based on the Voronoi diagram and
Delaunay triangulation.
fsr 1.0.1
Major changes
Added a new construction policy in the spa_creator()
function based on the convex hull (an improved implementation from the
issue #29).
Minor changes
Added the publication that describes the fsr
package into CITATION.
Added an optional parameter in spa_creator() named
digits (an improved update based on the pull request #28 - @leticiabohnert).
Bug fixes
Fixed spa_add_component() for checking a specific
condition.
Fixed the management of CRS when plotting spatial plateau objects
(fsr_plot()).
Fixed the management of geometry collections resulting from some
geometric computations of the spatial plateau geometric set
operations.
fsr 1.0.0
This is the first release of fsr that consists of the
following modules:
Fuzzy Spatial Inference Module (e.g., functions to create a fuzzy
spatial inference model and functions to evaluate it).
Fuzzy Spatial Data Handling Module (e.g., fuzzy numerical
operations, fuzzy geometric set operations, and fuzzy topological
predicates).
Construction Module (e.g., spa_creator()).
Basic Module (e.g., S4 classes and basic functions).
