leaflet.circlesector: An R wrapper for the Leaflet.Circle-sector plugin A hatched nest with a fan of turtle hatchling tracks oritented towards the ocean

The R package leaflet.circlesector wraps the Leaflet plugin Leaflet.Circle-sector, providing a way to draw circle segments on leaflet maps.

This can be used to visualise marine turtle hatchling (mis)orientation at the time of nest emergence.

See vignette("Introduction") for an explanation of packaged example data and desired visualisation.

library(leaflet.circlesector)
data("fans_tracks")
data("fans_mean")
data("fans_water")
data("outlier_segments")

leaflet_basemap(l_height = 500, l_width = 700) %>% 
    leaflet::clearBounds() %>% 
    leaflet::addCircles(
        data = fans_tracks,
        lat = ~ lat,
        lng = ~ lon,
        color = 'white',
        weight = 2,
        radius = 5
    ) %>%
    addCircleSectorMid(data = fans_mean) %>%
    addCircleSectorMid(data = fans_water) %>%
    addCircleSectorMid(data = outlier_segments) %>%
    addCircleSectorMinMax(data = fans_tracks) %>% 
    leaflet::setView(115.0245, -21.46, 19)
