Every time i insert : A<-lm(GandW ~ Authocracy;Data) i get this error: Error: unexpected input in "A<-lm(GandW ~ Authocracy,Data)" 

Iam using Mac.  And i have checked that "Data" has been read correctly. The same command with the same Data has been used by a friend who is using Linux, and its works for him. 
I have now tried many things but without any results. 


Thanks for help!
