subset,ctd-method: Subset a CTD Object

Description

This function is somewhat analogous to subset.data.frame, but only one independent variable may be used in subset in any call to the function, which means that repeated calls will be necessary to subset based on more than one independent variable (e.g. time and distance).

Usage

Arguments

x

A ctd object, i.e. one inheriting from ctd-class.

subset

An expression indicating how to subset x.

...
