check_existing: Check existing sample data against requirements

In tgoodbody/sgsR: Structurally Guided Sampling

Check existing sample data against requirements

Description

This function checks whether the existing sample data meets certain requirements for use in downstream analyses.

Usage

check_existing(existing, raster, nSamp, plot = FALSE, details = NULL)

Arguments

existing	sf 'POINT'. Existing plot network.
raster	SpatRaster. Raster to guide the location of the samples. If type = "clhs" this raster can also be used to define the population distributions to be used for sampling.
nSamp	Numeric. Number of desired samples.
details	Logical. If FALSE (default) output is sf object of systematic samples. If TRUE returns a list of sf objects where tessellation is the tessellation grid for sampling, and samples are the systematic samples.

Value

If requirements are met, the function returns the prepared existing sample data. Otherwise, it raises a stop error with a relevant message.
