oce (version 0.9-21)

subset,section-method: Subset a Section Object

Description

This function is somewhat analogous to subset.data.frame. The condition set by subset may be in terms of stationId or any combination of longitude, latitude and time. However, stationId may not be combined with the others; to get that effect, call this function more than once.

Usage

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

Arguments

x

A section-class object.

subset

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

...

Optional arguments, which may include indices, a vector of the indices of stations to be kept (starting at 1 for the first station).

Value

A new section object.
