Usage

parse_precis_forecast(state, filepath)

Arguments

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 pr<U+00E9>cis file(s) to parse. See Details for more.

Value

A data.table of Australia BOM pr<U+00E9>cis seven day forecasts for BOM selected towns. For full details of fields and units returned see Appendix 2 in the bomrang vignette, use vignette("bomrang", package = "bomrang") to view.

Details

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

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_precis_forecast()`, provided that the files are all present in the directory.
