I am attempting to use Muxviz, and I believe that I installed all of the required dependencies (octave, R, g++, gfortan, and GDAL), but I'm getting an error when I try to use "source('muxVizGUI.R')". I says
Error in if (grep("3.2", version$version.string) != 1) { :
argument is of length zero
Any suggestions? I just made sure that R is > 3.2.x.
