S3 Ops Group Generic Functions for stars objects

Description

Ops functions for stars objects, including comparison, product and divide, add, subtract

Usage

## S3 method for class 'stars'
Ops(e1, e2)

## S3 method for class 'stars'
Math(x, ...)

## S3 method for class 'stars_proxy'
Ops(e1, e2)

## S3 method for class 'stars_proxy'
Math(x, ...)

Arguments

e1	object of class stars
e2	object of class stars
x	object of class stars
...	parameters passed on to the Math functions

Details

if e1 or e2 is is a numeric vector, or e2 has less or smaller dimensions than e1, then e2 is recycled such that it fits e1, using usual R array recycling rules. The user needs to make sure this is sensible; it may be needed to use aperm to permutate dimensions first.

Value

object of class stars

Examples

tif = system.file("tif/L7_ETMs.tif", package = "stars")
x = read_stars(tif)
x * x
x / x
x + x
x + 10
all.equal(x * 10, 10 * x)
tif = system.file("tif/L7_ETMs.tif", package = "stars")
x = read_stars(tif)
a = sqrt(x)
b = log(x, base = 10)
