(b) Mar

(c) Char

(d) Ian

I had been asked this question during an interview.

I would like to ask this question from Graphics with R in portion Distributions, Graphics & Neural Networks of R Programming

Answer 1

The correct answer is (b) Mar

For explanation I would say: The graphical parameter mar defines how many lines appear in each of the four margins. So mar is an alternative way of defining margins.
