subset,adv-method {oce} | R Documentation

## 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.

### Value

A new adv object.
