create_Hashes: Create Hashes

In CCAMLRGIS: Antarctic Spatial Data Manipulation

Create Hashes

Description

Create hashed lines to fill a polygon.

Usage

create_Hashes(pol, angle = 45, spacing = 1, width = 1)

Arguments

pol	single polygon inside which hashed lines will be created. May be created using create_Polys or by subsetting an object obtained using one of the load_ functions.
angle	numeric, angle of the hashed lines in degrees (0-360), noting that the function might struggle with angles 0, 180, -180 or 360.
spacing	numeric, spacing between hashed lines.
width	numeric, width of hashed lines.

Value

Spatial object in your environment, to be added to your plot.
