• ‘st_connect’ lines snap to polygon/line outline instead of centroid
• Added new examples
• Fixed progress bar issues
• Changed formatting in vignette

nngeo 0.2.0 (2018-07-18)

• Added OpenMP support
• Added ‘dist’ (sampling point interval) parameter for ‘st_connect’
• Fixed progress bar issues in ‘st_connect’
• Switched from ‘for’ loop to ‘lapply’ in ‘st_connect’

nngeo 0.2.1 (2018-07-21)

• Removed OpenMP support due to issue with Solaris

nngeo 0.2.2 (2018-09-29)

• Using ‘STRICT_R_HEADERS’ in Rcpp

nngeo 0.2.4 (2018-12-06)

• Added ‘st_ellipse’ function
• Added ‘st_remove_holes’ function

nngeo 0.2.7 (2019-03-12)

• Added ‘st_postgis’ function
• Added ‘st_segments’ function

nngeo 0.2.8 (2019-05-12)

• Change C code fron ‘distance.c’ to ‘GeographicLib’
• Use C code through the C API instead of ‘Rcpp’

nngeo 0.2.9 (2019-08-07)

• Added ‘raster_focal’, a wrapper around ‘raster::focal’
• Added ‘raster_clump’, a wrapper around ‘raster::clump’
• Added ‘raster_slope’ and ‘raster_aspect’, wrappers around ‘raster::terrain’ for calculating topographic slope and aspect rasters
• Added ‘raster_extract’, a wrapper around ‘raster::extract’
• Added ‘raster_trim’, a wrapper around ‘raster::trim’

nngeo 0.3.0 (2019-12-03)

• Added ‘raster_extend’, a wrapper around ‘raster::extend’
• When using ‘returnDist=TRUE’, distances are now returned as sparse ‘list’ rather than a ‘matrix’

nngeo 0.3.4

• ‘st_nn’ with ‘returnDist=TRUE’ returns named list with elements ‘nn’ and ‘dist’
• Replaced ‘towns’ dataset
• Removed ’raster_*" functions
• Added ‘focal2’ function (a 3x3 focal filter on ‘stars’)
• Added ‘line’ and ‘pnt’ sample data (based on pgRouting tutorial)
• Added ‘st_split_junctions’ function
• ‘st_connect’ now uses ‘st_nearest_point’ rather than point sampling
• ‘st_connect’ removes CRS before calculating nearest point, to omit the warning when using lon-lat

Other ideas:

• Add ‘split line to equal parts’ function
• Add ‘round coord’ function
• Add ‘extend lines’ function
• Add ‘bridge lines to network’ function
• Add parallel processing option
• Add ‘st_az’ function
• Geodesic buffer
• ‘igraph’ object from layer based on proximity
• 3D distance of ‘POINT Z’ layers
