I doubt very much that 'randomPoints' is a base function. You are asked to include the names of contributed packages. Failing to do so implies that you expect us to go search for the package. I used to do so but have abandoned that action since it implicitly encourages inconsiderate behavior.

If we knew what structure  the 'evaluate' function in the unnamed package was returning, we might be able to help. There is probably either an S3-print method or an S4-show method that is displaying that text but such results are not always a good guide to what is returned as the object from a function.
