nfline

This is a simple interface over abline meant to be used along with the Hough transform. In the Hesse normal form (theta,rho), a line is represented as the set of values (x,y) such that cos(theta)*x + sin(theta)*y = rho. Here theta is an angle and rho is a distance.
See the documentation for hough_lines.

Fast image processing for images in up to 4 dimensions (two spatial
dimensions, one time/depth dimension, one colour dimension). Provides most
traditional image processing tools (filtering, morphology, transformations,
etc.) as well as various functions for easily analysing image data using R. The
package wraps 'CImg', <http://cimg.eu>, a simple, modern C++ library for image
processing.
