This is mainly intended for internal use within the package, e.g. by
read.odf(), and so the list of string-to-unit mappings is not
documented, since developers can learn it from simple examination
of the code. The focus of unitFromString() is on strings that are
found in oceanographic files available to the author, not on all
possible units.
Usage
unitFromString(unit, scale = NULL)
Value
A list() of two items: unit which is an
expression(), and scale, which is a string.
Arguments
unit
a character value indicating the unit. These
are matched according to rules developed to work with actual
data files, and so the list is not by any means exhaustive.
scale
a character value indicating the scale. The default value
of NULL dictates that the scale is to be inferred from the unit. If
a non-NULL value is supplied, it will be used, even if it makes no sense
in relation to value of unit.
