oce (version 0.2-1)

magic: Find the type of an oceanographic data file

Description

Find the type of an oceanographic data file.

Usage

magic(file, debug=getOption("oceDebug"))

Arguments

file

a connection or a character string giving the name of the file to be checked.

debug

an integer, set non-zero to turn on debugging. Higher values indicate more debugging.

Value

• A character string indicating the file type, or "unknown", if the type cannot be determined. If the result contains "/" characters, these separate a list describing the file type, with the first element being the general type, the second element being the manufacturer, and the third element being the manufacturer's name for the instrument. For example, "adp/nortek/aquadopp" indicates a acoustic-doppler profiler made by NorTek, of the model type called AquaDopp.

Details

This function tries to infer the file type, based on either the data within the file or, more rarely, based on the file name.
