# run filter module stand-alone
if (interactive()) {

library(oceanexplorer)

ui <- fluidPage(filter_ui("filter"), plot_ui("worldmap"))

# server
server <-function(input, output, session) {
 # table
 filter <- filter_server(
  "filter",
  reactive(NOAA),
  external = reactiveValues(lon = 190, lat = 33, depth = 20),
  variable = reactiveValues(variable = "temperature")
 )

 # plot data
 output_plot <- plot_server("worldmap", reactive(NOAA), filter$coord)
