Examples

## The \pkg{dwd2r} provides some mock data so its internal
  ## functions can be tested and developed without downloading
  ## any content from the DWD server. At the package's root
  ## directory call this function in the following way.
  dwd2r:::extract.content.climate( "03987",
    list( historical = file.path(
            system.file( "inst", package = "dwd2r" ), "res",
            "produkt_03987_potsdam_historical_mock.zip" ),
          recent = file.path(
            system.file( "inst", package = "dwd2r" ), "res",
            "produkt_potsdam_recent_03987_mock.zip" ) ),
          "tmpRecent", "tmpHistorical", "xts" )
