As you suggested, David, the code below works.
Now I it can find the weights - because they are in the data frame x.
But how can I be sure now that it actually grabs the data from the
data frame "variables" and not the data frame x?
x<-data.frame(y=rnorm(100,0,1),a=rnorm(100,1,1),b=rnorm(100,2,1),

I've already tried to define the weights outside of the function - and
it finds them.
But shouldn't it go in this order?
