himach (development version)

himach 0.3.2

CRAN release: 2023-09-20

  • New graphics: Route density charts, for routes combined with forecasts. See the Advanced Vignette.
  • Bug fixes: package dependencies, package documentation.

himach 0.3.1

CRAN release: 2022-12-05

  • Bug fixes: Prettier cutting of background map at dateline.
  • Dependency upgrades
  • using edition 3 of testthat
  • removing deprecated syntax in tidyverse

himach 0.3.0

CRAN release: 2022-06-09

  • New graphics options: in map_routes colour lines by a flight frequency variable or by number of accelerations to supersonic; now can also plot a simple speed/distance/time/altitude profile with profile_routes.
  • Added a section on cache housekeeping to the advanced vignette.
  • Bug fixes: Solved map ‘leakage’ at dateline, and make_AP2 copes with vectors of airport pairs correctly now.

himach 0.2.3

CRAN release: 2021-12-01

  • Fixes for solaris running old GDAL: switch to storing crs_Atlantic etc as strings.

himach 0.2.2

CRAN release: 2021-11-21

  • Fixed crash when routing over very short hops (say for re-positioning flights).
  • (development) Bug fixes: map leakage solved, summarise_routes now works with 3-letter airport codes as well as 4 (though default is still ICAO codes, not IATA codes for airports).
  • Removed use of Travis for code coverage.

himach 0.2.1

CRAN release: 2021-06-17

  • Patch so that tests work ok with sf v1.0+.

himach 0.2.0

  • More precise estimate of time penalty for acceleration from subsonic to supersonic cruise (or v.v.). Perhaps 1% difference in timings as a result.
  • Faster map plots, since maps are simplified (a little) now, by default.

himach 0.1.2

CRAN release: 2021-04-30

  • Tweak test for CRAN.
  • Fixed issue when using package functions without loading package.

himach 0.1.1

CRAN release: 2021-04-23

  • Fixing check errors on other platforms
    • Errors involving “NULL: PROJ available?” appear linked to this ‘older GDAL’ issue in sf. So implemented a work-around in various examples and vignettes.
    • Use make_aircraft(warn = FALSE) in examples & vignettes just to eliminate warnings. Still think this merits a warning in normal use, because the default aircraft are unlikely to be fit for purposes beyond testing.
    • bug fix: Mach 0.84 comparison from summarise_routes now uses 0.84 instead of 0.85.

himach 0.1.0

CRAN release: 2021-04-15

  • First version targeted for CRAN release.
  • Fixes a number of bugs in the avoid-area functionality.

himach 0.0.2

  • Major overhaul of the approach to smoothing from a Dijkstra-style route to a great-circle route, to handle the 1% of cases where the old approach didn’t work well.
  • Further speed improvements.

himach 0.0.1

  • First version using the s2 capabilities of the sf package. This gives more robust plotting, and a number of internal speed improvements.
