mask_source_area: Mask footprint to its analytical source area

In grahamstewart12/footprints: What the Package Does (One Line, Title Case)

Description

As the analytical footprint approaches 100%, the coverage increases rapidly over area that contributes little to the total measured flux (Matthes et al., 2014). Thus, it may be desirable to consider a percantage of the calculated footprint as the analytical footprint. This is acheived by masking the footprint to a given maximum cumulative weight.

Usage

mask_source_area(x, p = 0.85, mask_value = NA)

Arguments

x	The footprint as a numeric matrix or RasterLayer.
p	A numeric value between 0 and 1, recommended by Kljun et al. (2015) to be less than 0.9. Defaults to 0.85.
mask_value	A value to assign cells beyond the maximum percent weight. Defaults to NA, but 0 may be useful in some situations.

Value

An object of the same class as x, either a numeric matrix or RasterLayer.
