Question

Which function draws an axis on the current plot?

(a) axis()

(b) par()

(c) mar()

(d) jar()

This question was addressed to me by my school principal while I was bunking the class.

This is a very interesting question from Graphics with R in section Distributions, Graphics & Neural Networks of R Programming

Answer 1

Correct choice is (a) axis()

To elaborate: The axis() function draws an axis on the current plot. The side argument determines on which side it is to appear.
