r see how much memory an object takes

R for Windows FAQ

This allows a single process to take advantage of more than 4GB of RAM (if available) and for R’s memory manager to more easily handle large objects (in particular those of 1GB or more).

CS 352 Final Exam Study Guide - Rutgers University

May 06, 2016· To see how this contributes to overall delay, let us consider each link. If data is transmitted at R bits per second and a packet is L bits long, it takes L/R seconds to transmit a packet from one link to the next. Since transmission on the next link will not start until the packet is received, each link adds a delay of L/R seconds.
