Removing the statement (B <- 0) from the program will lead to an infinite loop because b is defined as 2 at the start and never changes its value through the program. Unless we change its value in the loop. (b <
The while loop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1.Note: remember to increment i, or else the loop will continue forever.BreakWith the break statement, we can stop the loop even if the while condition is...
The following syntax illustrates how to move to the next iteration in case a certain if-statement is TRUE. Let’s first create a basic for-loop in R:for(i in 1:10) { # Regular for-loop cat(paste("Iteration", i, "was finished.\n")) } # Iteration 1 was finished. # Iteration 2...
Initially, the outer loop assigns k=1L and executes its statement to the inner loop; meanwhile, the inner for loop assigns l=1L and prints k=1, l=1. And now, the inner loop executes itself as the information is true, and now ‘l’ is incremented to 1, will be set to l=2L, and...
As shown in Figure 2, the loop stops (or“breaks”) when our running index i is equal to the value 4. For that reason, R returns only three sentences. Example 2:nextwithin for-loop The next statement can be useful, in case we want to continue our loop after a certain break. The ...

for loops are a convenient shorthand that combines the initialization, condition check, and variable change in one place. The format of the for loop is: for (initialization; condition; loop operation) statement The initialization code executes before the for loop begins. The condition is tested ...
In programming,forloop is a kind of iteration statement which allows the block to be iterated repeatedly as long as the specified condition is not met or a specific number of times that the programmer knows beforehand. Afor loopis made of two parts: ...
Example 1: R repeat Loop Let's see an example that will print numbers using a repeat loop and will execute until the break statement is executed. x = 1 # Repeat loop repeat { print(x) # Break statement to terminate if x > 4 if (x > 4) { break } # Increment x by 1 x = x...
