Hello, I don't know if you can help me, but I have an issue when i try to install a package and launch it. You will find a picture of the screen and the messages that R returns to me. I don't understand what's is wrong and what should I do to make the setup of the package sucessful. I hope you could help me, Yours faithfully, Lucas Vignon -------------- next part -------------- A non-text attachment was scrubbed...
