Adaptation of <code><a href="/link/abline?package=terra&version=1.8-80" data-mini-rdoc="terra::abline">abline</a></code> that allows adding a horizonal or vertical lines to a map. This function will place the lines in the locations within the mapped area as delineated by the axes. It is meant to be used when you specifiy your own tick marks, such that <code>add_grid</code> does not work.

add_abline

Methods for spatial data analysis with vector (points, lines, polygons) and raster (grid) data. Methods for vector data include geometric operations such as intersect and buffer. Raster methods include local, focal, global, zonal and geometric operations. The predict and interpolate methods facilitate the use of regression type (interpolation, machine learning) models for spatial prediction, including with satellite remote sensing data. Processing of very large files is supported. See the manual and tutorials on <https://rspatial.org/> to get started. 'terra' replaces the 'raster' package ('terra' can do more, and it is faster and easier to use).
