Subset an adv Object

Description

Subset an adv (acoustic Doppler profile) object. This function is somewhat analogous to subset.data.frame(), except that subsets can only be specified in terms of time.

Usage

subset(x, subset, ...)

Arguments

x	an adv object.
subset	a condition to be applied to the data portion of x. See “Details”.
...	ignored.
