subset,adp-method: Subset an ADP Object

Description

Subset an adp (acoustic Doppler profile) object, in a manner that is function is somewhat analogous to subset.data.frame. For any data type, subsetting can be by time or distance, but these may not be combined; use a sequence of calls to subset by both. For the special case of AD2CP data (see read.adp.ad2cp), it is possible to subset to the "average" data records with subset="average", to the "burst" records with subset="burst", or to the "interleavedBurst" with subset="interleavedBurst"; note that no warning is issued, if this leaves an object with no useful data.

Usage

# S4 method for adp
subset(x, subset, ...)

Arguments

x

An adp object, i.e. one inheriting from adp-class.

subset

A condition to be applied to the data portion of x. See ‘Details’.

...

Ignored.

Value

A new adp-class object.
