Subset an adv Object

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

# S4 method for class 'adv'
subset(x, subset, ...)

Arguments

x

an adv object.

subset

a condition to be applied to the data portion of x. See “Details”.

...

ignored.

Value

A new adv object.
