Question

If you have a lot of objects that you want to save to a file, we use ________ function.

(a) save()

(b) save.image()

(c) serialize()

(d) deserialize()

This question was addressed to me in exam.

My question is based upon Textual Data Formats topic in chapter R – Data Storage, Formats, Objects and Operations of R Programming

Answer 1

Right choice is (b) save.image()

To explain: 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.
