Visualise hatchling fan angles #46

Open florianm opened 3 years ago

florianm commented 3 years ago

Create a new R package leaflet-hatchlings

Template for R package wrapping Leaflet functions: leaflet.extras
Leaflet plugin to draw semicircles: Leaflet-semicircle
Add helpers to translate wastd_data$nest_fans/nest_fan_outliers/nest_lightsources to data for Leaflet-semicircle
Use any other Leaflet plugin to visualise
Write-up of data and draft spec for visualisation see https://github.com/dbca-wa/Leaflet.Hatchlings (this repo can then probably go away, seeing all necessary Leaflet vis components already exist - semicircle, lines, points)

Leaflet.Circle-sector wrapper created as a new R package: https://dbca-wa.github.io/leaflet.circlesector/ Now we can add wastdr::map_fanangles as:

Prepare data as per generate_data
Plot data as per vignette "Introduction"
Integrate into turtleviewer2

Should refactor the data prep for fan angles into download wastd turtledata and use pmap for performance on mis_bearing and mean_bearing

florianm commented 2 years ago

Refactor done: expensive rowwise() calculations of misorientation and mean angles are pushed to download_wastd_turtledata. TODO: should write a wrapper for https://github.com/jieter/Leaflet-semicircle/blob/master/Semicircle.js which is available on npm using derivePoints and invokeMethod and see if we can leverage vectorised leaflet::circle().
