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 Select the correct answer from above options

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.
