Assertion for empty <stars> objects

Currently {stars} doesn't appear to have a formalised way to define and test empty objects. So, we re using stars::st_as_stars(matrix(NA)) to generate empty <stars>, and here we specify the function to test the emptiness of such objects.

Usage

is_stars_empty(x)

Arguments

x

an object of class <stars>

Value

logical, whether x is a <stars> object or not

For internal use only.
