Question

Point out the wrong statement?

(a) Renaming a variable in a data frame in R is surprisingly hard to do

(b) The mutate() function exists to compute transformations of variables in a data frame

(c) mute() function, which does the same thing as mutate() but then drops all non-transformed variables

This question was addressed to me in semester exam.

Asked question is from dplyr topic in section R – Data Storage, Formats, Objects and Operations of R Programming

Answer 1

The correct option is (c) mute() function, which does the same thing as mutate() but then drops all non-transformed variables

Easy explanation: The rename() function is designed to make this process easier.
