setWMSParams

R Documentation

Update WMS request parameters

Description

Change WMS parameters such as time, styles or cql_filter on an existing layer without rebuilding the map. In Shiny, call this on leafletProxy.

Usage

setWMSParams(map, layerId = NULL, group = NULL, ...)

Arguments

`map`	a map widget object created from `leaflet()`
`layerId`	the layer id
`group`	the name of the group the newly created layers should belong to (for `clearGroup()` and `addLayersControl()` purposes). Human-friendly group names are permitted–they need not be short, identifier-style names. Any number of layers and even different types of layers (e.g., markers and polygons) can share the same group name.
`...`	Named WMS request parameters to set, for example `time = "2022-11-10T21:00:00Z"`.

Value

the new map object

Examples

library(leaflet)
library(leaflet.extras2)

leaflet() %>%
  addTiles() %>%
  addWMS(
    baseUrl = "https://gibs.earthdata.nasa.gov/wms/epsg3857/best/wms.cgi",
    layers = "MODIS_Terra_CorrectedReflectance_TrueColor",
    layerId = "modis",
    options = WMSTileOptions(format = "image/jpeg", time = "2022-11-10")
  ) %>%
  setWMSParams(layerId = "modis", time = "2022-11-11")
