sfdep (development version)

  • Fixes bug with cli and closes #49

sfdep 0.2.4

  • Dexter Locke is now the maintainer of sfdep
  • Address failing CRAN checks h/t @rsbivand #43
  • Address bug in local Gi/* statistics

sfdep 0.2.3

  • remove readr suggestion to pass noSuggests from CRAN. Much minuscule tasks for the overlords.

sfdep 0.2.2

  • no changes from 0.2.1 version bump solely for CRAN

sfdep 0.2.1

  • Bivariate Moran uses the new spdep implementation which is faster. It does, however, return an object of class boot which needs extra work to calculate the p-value
  • Local join count univariate uses spdep now
  • adds graph based neighbors:
    • st_nb_delaunay() uses spdep::tri2nb()
    • st_nb_gabriel() uses spdep::gabrielneigh() and spdep::graph2nb()
    • st_nb_relative() uses spdep::relativeneigh() and spdep::graph2nb()
  • activate() is now exported as a generic method to no longer conflict with tidygraph
  • st_as_graph() now creates undirected graphs
  • new functions for sfnetworks
    • node_get_nbs(): converts the node adjacency list to a neighbor list
    • node_get_edge_list(): creates an edge adjacency list used to get edge attribute columns
    • node_get_edge_col(): uses the edge list to get edge attributes and turn them into a weight like list

sfdep 0.2.0

  • spatial_gini() is a new global measure
  • euclidean_median() is added for identifying the euclidean median of points for point pattern analysis.
    • Implemented using pracma::geo_median()
      • pracma is now added as a suggested package
  • center_mean() and center_median() are added for point pattern analysis
  • tally_jc() returns join count matrix via spdep::joincount.multi() as a data.frame object
  • st_complete_nb() creates a complete graph of neighbors
  • set operations for neighbor lists nb_union(), nb_intersect(), nb_setdiff()
  • st_block_nb() is introduced to create neighbor contiguity based on spatial regimes
  • critical_threshold() gains argument k to identify minimum number of neighbors when calculating threshold
  • pct_nonzero() calculates the percent of non-zero neighbors
  • szero() to calculate the global sum of weights
  • nb_as_matrix() and wt_as_matrix() convert neighbor and weights lists to matrices
  • two new functions include_self() based on spdep::include.self() and new remove_self() which is available separately in spdep due to issue 83 as spdep::remove.self().
  • local_g_perm() returns correct G statistic. Previously returned only the internal measure.
  • local_gstar() and local_gstar_perm() do not warn when self.included = TRUE
  • emerging_hotspot_analysis() implements emerging hotspot analysis with spacetime objects
  • a new spacetime class for linking spatio-temporal data and geometry
  • Implemented colocation quotient (CLQ) measures See the colocation vignette:
    • global_colocation() for global colocation of one categorical variable
    • pairwise_colocation() for asymmetric colocation of subcategories of one or two categories
    • local_colocation() for local CLQ measure
    • these functions are not fast! PRs welcomed to improve computation speed.
  • st_kernel_weights() now returns an attribute kernel which is set to the value of the kernel argument
  • cond_permute_nb() specifies SIMPLIFY = FALSE in internal mapply() call which was causing errors in creating conditionally permuted neighbor lists

sfdep 0.1.0

  • Released on CRAN!
  • Sending in for initial CRAN release
