Question

If we want to save individual R objects to a file, we use the _______ function.

(a) save()

(b) save.image()

(c) serialize()

(d) deserialize()

I got this question during a job interview.

The query is from Textual Data Formats in chapter R – Data Storage, Formats, Objects and Operations of R Programming

Answer 1

Right answer is (a) save()

The explanation is: 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.
