Question

What is the memory limit in R for 64 bit system?

(a) 8 TB

(b) 9TB

(c) 10TB

(d) 16TB

The question was posed to me in a national level competition.

This is a very interesting question from Functions topic in portion Control Structures, Functions, Scoping Rules, Loop Functions and Debugging of R Programming

Answer 1

Right choice is (a) 8 TB

Easy explanation: 8TB is the memory limit for 64-bit system memory and 3GB is the limit for 32-bit system memory. A solid understanding of R’s memory management will help you predict how much memory you’ll need for a given task.
