himach v1.0.0

himach is now pretty stable, so we've upped the version number to 1.0.0

The changes for this release are relatively minor: a broken link in a vignette, no longer using the global option 'quiet' to control messaging since this causes problems with devel R (see "himach.verbosity" instead), and clarifying that the use of the pipe |> means that minimum R version is 4.1.0

himach 0.3.1

In this patch:

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

himach v0.3.0

• 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.

Now on CRAN.

himach v0.2.3

Since the last release:

• 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).
• and then made it work on solaris running old GDAL: switch to storing crs_Atlantic etc as strings.

himach v0.2.1

Since the last Github release, there have been:

himach 0.2.1

• 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.

Clean sweep of CRAN checks.

himach 0.1.2

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

First version that clears all CRAN checks. Ta dah!

Tweaks for older platforms.

himach 0.1.1

This is mainly to fix errors when rolling out v0.1.0 to older platforms. The cost is that the small (New Zealand) test sets need to be accessed through a function rather than directly.

• 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.
• bug fix: Mach 0.84 comparison from summarise_routes now uses 0.84 instead of 0.85.
