rastersOverTime(input, output, session, rctRasterList, rctUrlTemplate,
  rctPolygonList, rctChosenPolyName, defaultPolyName = NULL,
  map = leaflet(), mapTilesDir = "www/", colorPalette,
  histTitle = "", sliderTitle = "", mapTitle = "", nPolygons,
  nRasters, rasterStepSize = 10)

Arguments

id

An id string that corresponds with the id used to call the module's UI function.

input

shiny server input object

shiny server output object

session

shiny server session object

rctRasterList

The name of the default selected polygon.

map

Leaflet map to show raster and polygons on.

mapTilesDir

Title to be shown above the histogram.

sliderTitle

Title to be shown above the slider.

mapTitle
