Add filters to a layer — add_filters • maplamina

Registers one or more filters for a layer. When multiple layers share the same bind, controls merge across layers by (bind, label, type).

Usage

add_filters(map, ..., id = NULL, bind = NULL, position = NULL, layer_id = NULL)

Arguments

map: A maplamina widget created by maplamina().
...: One or more filter_range() / filter_select() objects (or a single list of them).
id: Optional id used as a shorthand bind id when bind is omitted.
bind: Bind group id for shared UI control.
position: Optional UI position hint (applied to the control group).
layer_id: Target layer id (defaults to the most recently added layer).

Value

The modified map widget.

Examples

d <- data.frame(
  lon   = runif(1000, -60, 60),
  lat   = runif(1000, -60, 60),
  value = runif(1000, 1, 10)
)
maplamina() |>
  add_circles(d) |>
  add_filters(
    filter_range(~value, default = c(4, 6)),
    bind = "filters"
  )
