subset,amsr-method: Subset an amsr 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. latitude and longitude).

Usage

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

Arguments

x

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

subset

An expression indicating how to subset x.

...

Ignored.

Value

An amsr object.
