Dear Martin thanks for your comprehensive instructions, had I found them earlier I would have saved at least 3 hours of problems... Everyone copies: "your Windows system 'PATH' variable needs to be adjusted once you've installed graphviz and before installing Rgraphviz " What if Rgraphviz is already installed? Trying every step proposed does not seem to work any more (I get "character (0)" when I try your check in R). How can I remove Rgraphviz from R in order to start everything again? Or are there other solutions to that?
