spatsoc 0.2.2 (2023-09-07)

fixed CRAN notes about number of cores/parallel process/threads PR 58

spatsoc 0.2.1

fixed CRAN notes PR 56

spatsoc 0.2.0

following R-spatial evolution, removed dependencies on retired spatial packages ( PR 50: PR 52, PR 53, PR 54 PR 55)
- spatsoc now depends on sf, units instead of rgeos and sp
- build_lines now returns an sf LINESTRING object
- build_polys now returns an sf POLYGON/MULTIPOLYGON object
- group_lines now accepts an input sf LINESTRING object (argument "sfLines") and internally uses sf::st_intersects, sf::st_buffer, etc instead of rgeos functions
- group_polys now accepts an input sf POLYGON/MULTIPOLYGON object (argument "sfPolys") and internally uses sf::st_intersects, sf::st_area, etc instead of rgeos functions. group_polys now returns area and proportion of overlap when area = TRUE with respective units using the units package
- tests, vignettes, manual updated
- added temporary package startup message until October 2023
