Description Usage Arguments Details Value Author(s) References See Also Examples

Parse local BOM daily coastal waters forecast XML file(s) and return a data frame for a specified state or territory or all Australia.

1	parse_coastal_forecast(state = "AUS", filepath)

`state`	Required value of an Australian state or territory as full name or postal code. Fuzzy string matching via `agrep` is done.
`filepath`	A string providing the directory location of the coastal forecast file(s) to parse. See Details for more.

Allowed state and territory postal codes, only one state per request or all using AUS.

ACT: Australian Capital Territory (will return NSW)
NSW: New South Wales
NT: Northern Territory
QLD: Queensland
SA: South Australia
TAS: Tasmania
VIC: Victoria
WA: Western Australia
AUS: Australia, returns forecast for all states, NT and ACT

The filepath argument will only accept a directory where files are located for parsing. DO NOT supply the full path including the file name. This function will only parse the requested state or all of Australia in the same fashion as get_coastal_forecast, provided that the files are all present in the directory.

A data.table of an Australia BOM Coastal Waters Forecast. For full details of fields and units returned see Appendix 5 in the bomrang vignette, use
