library(stplanr), making it less tied to sp. This is a continuation of the work to support sf and will make it easier for the package to work with alternative representations of geographic data.geo_select_aeq.sf() was fixed by Jakub Nowosad in pull #238od_aggregate.sf() was fixed making it much fastergeo_bb() supercedes bb2poly(). The new function can return polygons, points and matrix objects determined by the output argument. It also allows bounding boxes to be extended in metres, and scaled in x and y dimensions.geo_code() now uses nominatim by default to find locations on the maps.od_coords() takes a wide range of input data types to return a consistent output representing OD data as a data frame of origin and destination coordinates. This is used behind the scenes to make other functions more modular.Plans for the next release
route() function for routing. This is more flexible and user-friendly than the existing line2route() and route_*() functions it enhances.route_cyclestreet() now also called (correctly) route_cyclestreets()geo_code() function replaces dependency on RGoogleMapsgoogle_dist() fixedcombinations added to sum_network_routes() so it runs quicker - see pull/177.sum_network_routes(), weightfield() and find_network_nodes() - see e.g. example(sum_network_routes) for details.l_poly added.SpatialLinesNetwork() fixed._each() dplyr functions replaced with equivalent _at or _all functions. See here for more.vignette("stplanr-paper") for details.introducing-stplanr vignette has been updated. It now provides a more basic introduction for people new to R for spatial and transport data.line2route() has been refactored to improve error detection and allow n_processes arguments. Thanks @nikolai-b. See pull/151 for details.line_match() function added, a wrapper around rgeos::gDistance(), to find similar routes.od_aggregate() and sp_aggregate() have been added, to enable OD data to be aggregated to new geographic levels.#141 fixed: viaroute() works again.bidirectional = TRUE returns a different result in line_bearing() now.onewayid() is now a generic function, meaning it can handle spatial and non-spatial dataline2route() allow you to specify variables to join-by - also has updated and more sensible defaultsod_id_order() to put origin-destination ids in order, to identify 2 way duplicates (split out from onewayid())route_cyclestreet() leading change_elev and av_incline being wrong now fixedNEW FEATURES
od2line(). See example(od2line) for an example.destinations for showing how OD matrix with destinations can be converted to spatial datalist_output allows the route information to be saved as a list, allowing save_raw = TRUE (which does not return a Spatial object) to be passed to the route_ function.BUG FIXES
line2route() (#124) fixedNEW FEATURES
New function reproject() is a simple wrapper around spTransform() that uses crs_select_aeq() to convert a spatial object in geographic (lat/lon) coordinates into on with projected coordinates, with units of 1 m. This is useful for various spatial operations, such as finding the length and area of an object.
Implement gprojected(), a function for performing GIS operations on a temporary, projected, version of spatial objects.
Addition of line_bearing() to return the bearing of lines based on start and end points.
Addition of angle_diff() for finding the angular difference between lines: are they roughly parallel or perpendicular?
BUG FIXES
line2df() now works on lines with multiple vertices and is faster.
Fixes in the examples used to illustrate how od_dist() works.
NEW FEATURES
Update to OSRM functions to support API v5.
New parameter byvars in the overline() function, to allow disaggregation of results by a grouping variable (see example(overline)).
Faster implementation of od2line(): od2line2(). Plan is to replace the original if no issues are found with new implementation.
New function od2odf() which converts OD data into a dataframe of origins and destinations (feeds od2line2() but also useful as self-standing function).
New argument new_proj in buff_geo() allows the results to be exported to any coordinate reference system (CRS).
New function gprojected() generalises concept of buff_geo(), building on crs_select_aeq() to allow any GIS query to be conducted on a temporary projected version of spatial objects with geographical CRSs.
New function od_dist() can quickly calculate Euclidean distances of OD pairs without converting to spatial objects.
BUG FIXES
Bug fix in onewayid() so it captures all lines.
Various improvements to documentation and code.
NEW FEATURES
Interface to the Google Distance Matrix API with dist_google.
New transport planning API added, with route_transportapi_public (for testing).
Update to line2route, allowing it to accept different routing funtions via the new argument route_fun (for testing - tested with route_fun = route_cyclestreet).
New functions for creating origin-destination data frames (point2odf) and SpatialLinesDataFrames (points2flow).
Addition of n_vertices and is_linepoint for identifying the number of vertices in spatial objects and whether the ‘line’ is really a point.
BUG FIXES
line2route refactored, with 10 fold speed increases on large (1000+) batches of lines.NEW FEATURES
Addition of new class definition SpatialLinesNetwork, methods for plot and summary and functions calc_network_routes and find_network_nodes allowing fast route calculations via igraph and other network analysis functions.
Functions for removing beginning and end of lines: toptail and toptailgs. Helper functions buff_geo, crs_select_aeq and line2points added.
Functionality for reading in the UK’s stats19 data: read_stats19_* functions download, unzip and re-categorise the data.
read_table functions added for reading Australian OD data.
decode_gl added to decode Google polylines and other functions for querying and reading data from OSRM services.
gtfs2sldf added to import GTFS routes as SpatialLinesDataFrames.
