But i think if you were given a list like that, you could square it and get a polynomial list.  I think any linear list can be transformed into a function if you mess with it enough o.O

When it gets complicated enough you might as well use seq(

But after a couple of tries, the binomcdf( thing creates a list of 100 elements in just 2 seconds, compared to 8.6 for the seq( equivalent, so it's gonna be faster for most cases, unless you need something really complex
