  Hi,

Try with ".":
model<- lm(y~., data=data)

 From ?formula:
"There are two special interpretations of |.| in a formula. The usual 
one is in the context of a |data| argument of model fitting functions 
and means 'all columns not otherwise in the formula': see |terms.formula 
<http://127.0.0.1:24287/library/stats/help/terms.formula>|."

HTH,
Ivan
