construct_buffer

Description

Internal function to construct plot area around coordinates

Usage

construct_buffer(coords, shape, size, return_sp, verbose)

## S3 method for class 'SpatialPoints'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

## S3 method for class 'SpatialPointsDataFrame'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

## S3 method for class 'MULTIPOINT'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

## S3 method for class 'POINT'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

## S3 method for class 'sf'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

## S3 method for class 'sfc'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

## S3 method for class 'matrix'
construct_buffer(coords, shape, size, return_sp = TRUE, verbose = TRUE)

Arguments

coords

SpatialPoints or 2-column matrix with coordinates of sample points
shape

String specifying plot shape. Either "circle" or "square"
size

Size of sample plot. Equals the radius for circles or the side-length for squares in mapunits
return_sp

If true, SpatialPolygons are returned.
verbose

Print warning messages.

Value

matrix or SpatialPolygons

Examples

coords <- matrix(c(10, 5, 25, 15, 5, 25), ncol = 2, byrow = TRUE)
construct_buffer(coords = coords, shape = "square", size = 5)
