Question

Which package can be integrated with dplyr for large fast tables?

(a) Table

(b) Data, dplyr

(c) Data.table

(d) Dplyr.table

The question was posed to me during an interview.

This is a very interesting question from Functions topic in section Control Structures, Functions, Scoping Rules, Loop Functions and Debugging of R Programming

Answer 1

Correct option is (c) Data.table

The best I can explain: Data.table package can be integrated with dplyr for large fast tables. dplyr package is used to speed up data frame management code. dplyr is a package for data manipulation, written and maintained regularly by Hadley Wickham.
