The beloved and nowadays deprecated goto found in Assembler, Basic, Fortran and similar programming languages of that generation, was a mean to tell the computer to jump to a specified instruction label: so, by placing that label before the location of the goto instruction, one obtained a repetition of the desired instruction a loop. In modern вЂ“ and not so modern вЂ“ programming languages, where a program is a sequence of instructions, labeled or not, the loop is an evolution of the вЂjumpвЂ™ instruction which asks the machine to jump to a predefined label along a sequence of instructions. Even for вЂcalculating machinesвЂ™, as computers were called in the pre-electronics era, pioneers like Ada Lovelace, Charles Babbage and others, devised methods to implement such iterations. It is nothing more than automating a certain multi step process by organizing sequences of actions (вЂbatchвЂ™ processes) and grouping the parts in need of repetition. вЂLoopingвЂ™, вЂcyclingвЂ™, вЂiteratingвЂ™ or just replicating instructions is quite an old practice that originated well before the invention of computers. Want to learn even more on loops? Start the DataCamp interactive R programming tutorial for free. And then try to get rid of those whenever the effort of learning about vectorized alternatives pays in terms of efficiency. In general, the advice of this R tutorial on loops would be: learn about loops, because they offer a detailed view of what it is supposed to happen (what you are trying to do) at the elementary level as well as an understanding of the data you are manipulating. We will present a few looping examples then criticize and deprecate these in favor of the most popular vectorized alternatives (amongst the very many) available in the rich set of libraries that R offers.
