The goal of rmsssim is to provide an R interface for the MS-SSIM image comparison metric. This was not written by me, gzt, this was imported from spatialcompare, which has a number of other functions I am not interested in and some dependencies that no longer work for me. This package depends on raster.

You can install this from github with:

#install.packages('devtools')
devtools::install_github('gzt/rmsssim')

Installing this may still be a bit frustrating, as rgdal is non-trivial to get working. On Fedora, make sure to run dnf install proj proj-epsg proj-devel gdal gdal-devel first. On other systems, change the commands accordingly. This StackOverflow answer has some guidance.
