This question was posed to me during an interview for a job.

Enquiry is from Functions in portion Control Structures, Functions, Scoping Rules, Loop Functions and Debugging of R Programming

Answer 1

Correct choice is (a) Transpose()

To explain I would say: Transpose t () is the easiest method for reshaping the data before analysis. The transpose (reversing rows and columns) is always the simplest method of reshaping a dataset. Use the t() function to transpose a matrix or a data frame.
