Extract.msr: Extract Subset of Signed or Vector Measure

In spatstat.core: Core Functionality of the 'spatstat' Family

Extract Subset of Signed or Vector Measure

Description

Extract a subset of a signed measure or vector-valued measure.

Usage

## S3 method for class 'msr'
x[i, j, ...]

Arguments

x	A signed or vector measure. An object of class "msr" (see msr).
i	Object defining the subregion or subset to be extracted. Either a spatial window (an object of class "owin"), or a pixel image with logical values, or any type of index that applies to a matrix.
j	Subset index selecting the vector coordinates to be extracted, if x is a vector-valued measure.
...	Ignored.

Details

This operator extracts a subset of the data which determines the signed measure or vector-valued measure x. The result is another measure.

Value

An object of class "msr".

   rp[square(0.5)]
   rs[ , 2:3]
