As you say, I did indeed have a locale problem. I've never had any  
reasons to worry about locale settings before and therefore know  
hardly anything about them, but if I change the locale according to  
Sys.setlocale("LC_CTYPE", "C") plotting works like a charm. However, I  
have to change the locale every time I start a new session. Is there a  
way to permanently change this setting?

Thank you all for your help!

Best regards,

Martin.
