bounding_wkt: Generate Bounding Boxes

Description

bounding_wkt takes bounding boxes, in various formats, and turns them into WKT POLYGONs.

Usage

bounding_wkt(min_x, min_y, max_x, max_y, values = NULL)

Arguments

min_x

a numeric vector of the minimum value for x coordinates.

min_y

a numeric vector of the minimum value for y coordinates.

max_x

a numeric vector of the maximum value for x coordinates.

max_y

a numeric vector of the maximum value for y coordinates.

values

as an alternative to specifying the various values as vectors, a list of length-4 numeric vectors containing min and max x and y values, or just a single vector fitting that spec. NULL (meaning that the other parameters will be expected) by default.

Value

a character vector of WKT POLYGON objects

See Also

wkt_bounding(), to turn WKT objects of various types into a matrix or data.frame of bounding boxes.

Examples

# NOT RUN {
# With individual columns
bounding_wkt(10, 12, 14, 16)

# With a list
bounding_wkt(values = list(c(10, 12, 14, 16)))
# }
