lapply takes three arguments: (1) a list X; (2) a function (or the name of a function) FUN; (3) other arguments via its ... argument. If X is not a list, it will be coerced to a list using as.list. ## function (X, FUN, ...) ## { ## FUN <- match.fun(FUN) ## ...
We can insert a break in our for-loop as shown in the following R code: for(iin1:5){# for-loop with breakif(i==4){break}print(paste("This is step", i))} Figure 2: for-loop with break Function. As shown in Figure 2, the loop stops (or“breaks”) when our running index ...

For this task, we can use the next function as shown below:for(i in 1:10) { # for-loop containing next function if(i %in% c(2, 5, 8)) next cat(paste("Iteration", i, "was finished.\n")) } # Iteration 1 was finished. # Iteration 3 was finished. # Iteration 4 was finished...
The iterable created in the example above is [0, 1, 2].Using a While LoopYou can loop through the list items by using a while loop.Use the len() function to determine the length of the list, then start at 0 and loop your way through the list items by referring to their indexes....
execute the print function and loop back. In case the remainder is non zero, the if statement evaluates to TRUE and we enter the conditional. Here we now see thenextstatement which causes to loop back to thei in 1:10condition thereby ignoring the the instructions that follows (so theprint...

You'll learn more about the difference between while and for loops in a bit, but for now, concentrate on the following pieces that you need in order to create a for loop: The for keyword A variable The in keyword The range() function, which is an built-in function in the Python libr...
functionhello($name,LoopInterface$loop) {$loop->futureTick(function()use($name) {echo"hello$name\n"; }); }hello('Tester',$loop); Unlike timers, tick callbacks are guaranteed to be executed in the order they are enqueued. Also, once a callback is enqueued, there's no way to cancel...
In most computer programming languages, an infinite loop is not desirable, since it means that the program never terminates. However, when we are modeling digital systems, an infinite loop can be useful, since many hardware devices repeatedly perform the same function until we turn off the power...
