extract_SFSW2_cells_from_shp: Extract spatial polygon data for polygons or rectangles.

In DrylandEcology/rSFSW2: Simulation Framework for SOILWAT2

Description

Extract spatial polygon data for polygons or rectangles.

Usage

extract_SFSW2_cells_from_shp(x, y, fields = NULL, code = NULL, ...)

Arguments

x	A object inheriting from data are extracted.
y	Either an object inheriting from sp::SpatialPolygons OR resolution(s) of rectangles as a numeric vector of length two or a matrix with two columns. If sp::SpatialPolygons, then values of data are extracted per polygon and weighted by area. If the latter, then coords must be provided. y is the vector or matrix representing the rectangle extents in x- and y-coordinates. If a matrix, then rows must match coords.
fields	A character vector. If not NULL, then fields selects columns of the extracted object.
code	A vector. If not NULL, then the extracted data are treated as integer codes of a factor whose levels are encoded by code.
...	coords Cell centers (corresponding to each resolution of y) that are represented by a two-column matrix of xy-coordinates. Ignored if y is inheriting from sp::SpatialPolygons. crs_data A sp::CRS object indicating the coordinate reference system (CRS) of y and coords. Ignored if y is inheriting from sp::SpatialPolygons. probs A numeric vector of probabilities with values in [0, 1] at which sample quantiles are returned.

Value

A vector or matrix with length/rows corresponding to the elements of y and available columns requested by fields. If !is.null(code), then the encoded 'factor levels' are returned.
