Add views to a layer — add_views • maplamina

Registers a per-layer views component. When multiple layers share the same bind, a single selector control is created.

Usage

add_views(
  map,
  ...,
  id = NULL,
  bind = NULL,
  position = NULL,
  layer_id = NULL,
  duration = 750,
  easing = c("smoothstep", "linear", "easein", "easeout", "easeinout", "easeInOutCubic")
)

Arguments

map: A maplamina widget created by maplamina().
...: One or more view() objects (or a single list of them).
id: Optional component id (also used as the default bind id).
bind: Bind group id for shared UI control. If omitted, defaults to id (or an auto id).
position: Optional UI position hint (applied to the control group).
layer_id: Target layer id (defaults to the most recently added layer).
duration: Animation duration (ms) for switching views.
easing: Easing function name for switching views.

d <- data.frame(
  lon   = runif(1000, -60, 60),
  lat   = runif(1000, -60, 60),
  value = runif(1000, 1, 10)
)
maplamina() |>
  add_circles(d, radius = 5) |>
  add_views(
    view("magnitude", radius = ~value * 3),
    view("faint", fill_opacity = 0.2)
  )
