Plot NABEL data

Description:

     The National Air Pollution Monitoring Network (NABEL) provides
     time series data on air-borne pollutant concentrations from a
     network of measurement stations across Switzerland. The data can
     be queried with an HTML form (see sources). This is a simple
     function that serves as a wrapper for that HTML form. Its main
     purpose is to demonstrate some of the capabilities of
     <http://opencpu.org/> by Jeroen Ooms.

Usage:

       nabel(pollutant = c("o3", "no2", "so2", "co", "nmvoc", "pm10", "pm1", "cpc", "temp", "prec", "rad"),
         stations = c("Bern-Bollwerk", "Lausanne-César-Roux", "Lugano-Università", "Zürich-Kaserne", "Basel-Binningen", "Dübendorf-Empa", "Härkingen-A1", "Sion-Aéroport-A9", "Magadino-Cadenazzo", "Payerne", "Tänikon", "Lägeren", "Chaumont", "Rigi-Seebodenalp", "Davos-Seehornwald", "Jungfraujoch"),
         interval = c("hourly", "daily"),
         period = c("day", "week", "month", "free"),
         from = NULL, to = NULL)
     
Arguments:

pollutant: pollutant or meteorological variable to plot

stations: measurement stations (either by number or name) to include

interval: plot hourly or daily means

  period: time series period

    from: start day of time series period (if period = "free")

      to: end day of time series period (if period = "free")

Details:

     A single pollutant or meteorological variable is plotted (default
     is o3):

       1. o3 (Ozone (O3))

       2. no2 (Nitrogen dioxide (NO2))

       3. so2 (Sulfur dioxide (SO2))

       4. co (Carbon monoxide (CO))

       5. nmvoc (Non-methane volatile organic compounds (NMVOC))

       6. pm10 (Particulate matter (PM10))

       7. pm1 (Particulate matter (PM1))

       8. cpc (Particulate number concentration (CPC))

       9. temp (Temperature (TEMP))

      10. prec (Precipitation (PREC))

      11. rad (Global radiation (RAD))

     One or several measurement stations have to be included (default
     is to include all 16):

       1. Bern-Bollwerk

       2. Lausanne-César-Roux

       3.  Lugano-Università

       4. Zürich-Kaserne

       5.  Basel-Binningen

       6. Dübendorf-Empa

       7. Härkingen-A1

       8. Sion-Aéroport-A9

       9. Magadino-Cadenazzo

      10.  Payerne

      11. Tänikon

      12. Lägeren

      13. Chaumont

      14.  Rigi-Seebodenalp

      15. Davos-Seehornwald

      16.  Jungfraujoch

     For the time series measurement interval, you have a choice
     between hourly and daily means (default is hourly).

     The depicted time period can be the last day, week, month, or you
     can freely choose the period by specifying a start date with from
     and an end date with to (both need to be given in a format that
     can be converted to an object of class Date with as.Date() - e.g.
     in ISO 8601 format, i.e. YYYY-MM-DD).

Value:

     none (invisible NULL)

Note:

     Not all pollutants are measured at all stations.
