In this release we have made the following changes:

  • Changed the code used to test the version of PROJ on attach. The old approach used to create an error for sf < 1.0.
  • Adjusted one of the vignettes following the changes in dplyr 1.0.8.
  • Removed conflicting URL from package documentation spatial_edge_measures### New features
  • Updates to to_spatial_smooth() morpher:
    • Argument summarise_attributes added to summarise attribute values of concatenated edges. Refs #120.
    • Argument require_equal added to specify if and which attributes should be checked for equality before removing a pseudo node. Refs #124.
    • Argument protect added to specify nodes that should never be removed, even if they are a pseudo node. Refs #177.
    • Concatenated edges after smoothing are now allowed to cross themselves. Refs #117.
  • Updates to st_network_cost():
    • Duplicated nodes are now accepted in the to argument. Refs #183.
    • Cost matrix output now contains units. Refs #119.
    • Argument direction added to specify if outbound, inbound or all edges should be considered. This replaces the argument mode from igraph::distances(). The default is "out", while before it was "all". For undirected networks this argument is ignored.
  • Edge measure function gained an argument degrees which can be set to TRUE to return angles in degrees instead of radians.
  • By default st_network_paths() now encodes nodes by their name, whenever a name attribute is present in the nodes table. This can be disabled by setting use_names = FALSE. Refs #154.
  • Functions sf::st_precision() and sf::st_set_precision() now have a method for sfnetwork objects, such that coordinate precision can be queried and set. Refs #209.
  • Functions sf::st_intersection() and sf::st_difference() now have a method for sfnetwork objects, such that networks can be spatially clipped. The method for sf::st_crop() now uses the same workflow. These functions do not work yet on edges of undirected networks. Refs #133.
  • Function sf::st_drop_geometry() is now a generic and therefore got an sfnetwork method.
  • Several other sf functions got an sfnetwork method, merely to be consistent in the type of functions we provide a method for. Only those functions that mutate the geometry column of an sf object in such a way that would break the valid spatial network structure are not supported.
  • Methods for sf::st_coordinates(), sf::st_bbox() and sf::st_crs() gained an active argument such that this information can be extracted from any network element without first activating it. Refs #215.

Bug fixes

  • Rd files do not contain code anymore that is incompatible with HTML5. Refs #221.
  • Print methods now return x invisibly. Refs #217.

Refactoring

  • Error messages when edge measure or query functions are applied to a network with active nodes, or when node measure or query functions are applied to a network with active edges, are now more informative. Refs #216.
  • Calculating straight-line distances of edges is now more performant. Refs #180.
  • Edge measure function edge_circuity() does not return units objects anymore, since circuity is unitless.

Community

  • Vignettes updated to showcase new features.
  • Code of conduct updated according to newer template.
  • Contributing guidelines extended with templates for commit messages.
