Question

Which of the following d takes two columns and spreads them into multiple columns?

(a) ggmissplot

(b) printplot

(c) print.ggplot

(d) ggplot

I have been asked this question in final exam.

My doubt stems from Data Wrangling in section Profiling, Simulation and Data Analysis of R Programming

Answer 1

Correct answer is (c) print.ggplot

For explanation I would say: spread() makes “long” data wide.
