Visual Testing for Graphics in R
preprintposted on 06.01.2020, 01:32 by Paul Murrell
This report describes the 'gdiff' package for R, which provides tools for performing visual tests on graphical output. Visual testing is essential for checking that code is producing the correct graphical output. The goal of the 'gdiff' package is to support a wide range of testing scenarios, including testing graphical output between different versions of R.
