Question

If you explicitly want an integer, you need to specify the _____ suffix.

(a) D

(b) R

(c) L

(d) K

I have been asked this question during an online interview.

Question is from Data Types topic in section Nuts and Bolts and Getting Data In and Out of R Programming

Answer 1

Correct choice is (c) L

To elaborate: Entering 1 in R gives you a numeric object; entering 1L explicitly gives you an integer object.
