In mdsumner/sc: Common Forms for Complex Hierarchical and Relational Data Structures

silicate dev

• Removed all deprecated tidyselect uses of '.data$'.

• Fixed some conditional Suggests use, thanks to CRAN.

silicate 0.7.1

• Bump with more conditional suggests.

silicate 0.7.0

• Removed problematic example code.

• Resubmit to CRAN after missing archival deadline (package in suggests not used conditionally).

• ARC() really actually finally works.

• Fixed sc_coord() for Spatial #128.

• SC0() gains a TRI0 method.

• Another huge bug fix in ARC() doh.

• Add SC() and SC0() for pslg objects.

• Add function PATH_from_df() to generate PATH0 from generic data frame input.

• Fixed bug in TRI.TRI0 not propagating the object id.

silicate 0.6.0

• New TRI and TRI0 methods for mesh3d. No material properties yet, just one mesh object.

• Added TRI and TRI0 methods for sfc_GEOMETRYCOLLECTION to catch lists of POLYGON triangles. Rudimentary function now for TRI0/TRI (straight conversion), PATH0, ARC. Triangles automatically include z_ = 0 if not already present.

• New data set ear_gc a GEOMETRYCOLLECTION of POLYGON triangles.

silicate 0.4.0

• Fixed obscure bug that messed up anglr because of class-dropping for the sfc in a tibble. now 0.3.0.9040

• A potentially breaking change, stray uses of the triangle$visible_ property have been removed, to be consistent with the anglr package.

• Several fixes related to new unnest() behaviour, it was unnecessary so replaced with use of do.call/rbind.

• Fix previous unexported sc_vertex.SC0, the cause of https://github.com/hypertidy/anglr/issues/97.

• Fixed a problem with unclassed sfc lists. #109 and https://github.com/hypertidy/anglr/issues/91/.

silicate 0.3.0

• Import crsmeta so we can navigate the structure change in sf crs. (Fixes breakage in eixport).

• Fixed CRAN NOTE about not using geometry import.

• Fix deprecated usage of tibble. 1) Internal sf objects now have "list" in the class of the sfc column. 2) No matrix sub-assignment into columns of a tibble. See #105.

• New models TRI0 and PATH0 as analogues to SC0.

• Fixed off-by-one error in segment colours when plotting ARC. Fixes #101.

• Fixed unused geometry package import.

silicate 0.2.0

• Clarified Description and cleaned up examples, thanks to CRAN feedback.

• First viable release.

• Commited to ARC only being relevant to polygon layers.

• New models TRI0 and PATH0 as analogues to SC0.

silicate 0.1.1.9001

• sc_uid is now 6L characters by default, controlled by uid_nchar argument, and settable in option silicate.uid.size. If option(silicate.uid.type = "integer") this is ignored, but that is considered experimental for now.

• Models now have print methods.

• The filter method for SC is now exported.

• Incorporate new version of SC0 model, a better starting point for decomposing objects.

• SC can now interpret TRI, which allows for very easy DEL re-triangulations and fine control over the quality and details of the mesh

• TRI now allows linear topologies, they are assumed to be all island paths (see anglr::DEL for a possible better approach).

• SC and PATH now allow degenerate paths and edges, with plot as pixel and point respectively.

• TRI model now includes object_link_triangle, and drops object_ and path_ from triangle table to be consistent with anglr::DEL.

• The meta table is now always present in models.

• Migrated from JS rearcut to C++ decido for triangulation.

• Cleaned up the triangulation logic.

silicate 0.1.0

• added functions compact_indexes and expand_indexes to remove and restore the unique labels on entities - these are purely to explore what the minimal size of a model might be

• more consistency for sc_verbs, sc_coord, sc_vertex, sc_object, sc_node, sc_arc, sc_path, sc_uid

• established models SC, PATH, ARC, TRI

• removed PRIMITIVE

• (breaking) sc_uid now generic, with argument x (not n)

• various fixes in line with gibble 0.0.1.9002 to properly support sp structures

• fixed bug where a single-path data set exposed an offset assumption applied by sc_segment, fixes https://github.com/hypertidy/silicate/issues/40

• fixed bug where 0-column dataframe was assumed to be a list of vectors https://github.com/hypertidy/anglr/issues/55

• added polymesh data

• support for trip

• install flight_tracks example

• support for sp!

• moved sf specific facility from scsf

• renamed package

• sc_rand is deprecated, to be replaced by sc_uid

silicate 0.0.2

• (was called sc)
• cleaned up the un-join with a specific function from 'unjoin' package
• added internal function sc_edge, and exported sc_node and renamed arc_node to NARC
• removed all sf-specific facilities to external package
• revert to sf 0.2-7 to enable vignette migration
• PATH model added (with ongoing migration from "branch" term to "path" term)
• BRANCH model effectively removed, replaced by the PATH model
• PRIMITIVES model added, including bare-nodes arc_node function to return the 3-way nodes

silicate 0.0.1

• (was called sc)
• first functions, the BRANCH model for sf
