Question

.RData extension used when we save data using the functions ___________

(a) save()

(b) save.image()

(c) save and save.image functions

(d) serialize()

I got this question in an international level competition.

I want to ask this question from Textual Data Formats topic in section R – Data Storage, Formats, Objects and Operations of R Programming

Answer 1

Correct answer is (c) save and save.image functions

Easiest explanation: Save is used for saving an arbitrary number of R objects with a binary format (possibly compressed) to a file. The output of dput() can also be saved directly to a file. Save.Image can be used mostly in R.
