I've tried to contact the author of part of the FactoMineR package which was given as: Fran?ois.Husson at agrocampus-rennes.fr However, the cedilla is not liked by any mail system I have access to, so that address is a non-starter. I tried using a simple letter 'c' which didn't cause a syntax error, but achieved nothing else. Could it just be that the address was correct and it's the season in France for people to be away and so not answering email? Or is there something I should know about such characters in email addresses?
