Question

If a programmer wants the output to be a list then ___________ function is used. (a) Lapply (b) Sapply (c) Vapply (d) Zapply I got this question during an online interview. I want to ask this question from Functions in division Control Structures, Functions, Scoping Rules, Loop Functions and Debugging of R Programming Select the correct answer from above options

Answer 1

Right answer is (b) Sapply The explanation is: sapply() function does the same jobs as lapply() function but returns a vector. We can use a user built-in function into lapply() or sapply(). We create a function named avg to compute the average of the minimum and maximum of the vector.
