Description

Return a subset of a '>amsr object.

Usage

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

Arguments

x

an '>amsr object.

subset

an expression indicating how to subset x.

...

ignored.

Value

An '>amsr object.

Details

This function is used to subset data within an '>amsr object by longitude or by latitude. These two methods cannot be combined in a single call, so two calls are required, as shown in the Example.
