v 0.2.7

  • leader_direction_group function for calculating leadership defined as position within a spatiotemporal group along the mean direction of movement (PR 66)

  • removed temporary startup message warning of changes related to R-spatial evolution

v 0.2.6

New experimental functions:

  • direction_polarization function for calculating polarization of individual directions within spatiotemporal groups (PR 76)
  • direction_group function for calculating mean group direction (PR 91)

  • direction_step function for calculating direction in radians between each location (PR 90)

v 0.2.5

New experimental functions:

  • centroid_fusion function for calculation fusion centroids (PR 89)
  • centroid_group function for calculating group centroids (PR 72))

v 0.2.4

New experimental function:

  • fusion_id function for flexibly identifying fission-fusion events (PR 78)
  • improve tests of fusion_id with tests for expected number of output fusionIDs (PR 83)

v 0.2.3

  • Fix/replace igraph clusters with components (PR 61)
  • Fix/warnings from merge args (PR 62)

v 0.2.2 (2023-09-07)

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

v 0.2.1 (2023-08-23)

  • fixed CRAN notes (PR 56)

v 0.2.0 (2023-08-22)

  • 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 November 2024

v 0.1.17 (2023-03-16)

  • added a link to our spatsoc + targets workflow example
  • changed the error and underlying check for group_polys from alphanumeric to spaces in input DT's id column
  • clarify timegroups are required for group_pts, edge_nn and edge_dist (PR 46)
  • fix potential mixup between a column named splitBy and splitBy arg (PR 45)
  • fix links in man (PR 47)
  • fix proportions outside 0-1 due to differences in default units from rgeos::gArea and polys@area (PR 49)
  • Add keyword internal by @maelle (PR 40)
  • Rm unnecessary lines by @maelle (PR 43)

v 0.1.16 (2021-03-23)

  • added an option for edge_dist to handle threshold = NULL. If NULL, edge_dist will return all neighbours observed (eg. useful if one wanted to calculated mean nearest neighbour distance at each timegroup).
  • updated EPSG argument according to newest recommendations in tests, man and vignettes (PR 38
  • removed expect_silent tests (PR 37)
  • switched CI for tests and code coverage to GitHub Actions (PR 36)

v 0.1.15 (2020-10-21)

  • fix TZ=UTC data.table tests (Issue 32)

v 0.1.14 (2020-07-03)

  • updated tests, man and vignettes following new handling of projections in sp (PR 31, R spatial information)
  • clarified explicit drop of NAs in dyadID in edge list vignette

v 0.1.13 (2020-03-25)

  • added dyad_id function for generating dyad IDs with edge functions (PR 27)
