Do you want the count of remaining elements which are strictly
greater than the first element?

[1] 4
or perhaps a bit more deviously:
> sum( a[1]

In your example, you could have noted that summary had an element
named coefficients which was a 2 x 4 object, with names "(Intercept)"
and "x". Although you could have asked for the values with
coefficients[2,4], the use of names makes the intent more clear.
