R Loops - R Programming language

What are R Loops?

Usually statements are executed sequentially but if you encounter a situation to execute a block of code several number of times. Then,the first statement in a function is executed first, followed by the second, and so on.
Programming languages provide different types of control structures to support more complicated execution paths.
A loop statement is designed to execute a statement or group of statements multiple times. Below is the general form of a loop statement applied in most of the programming languages −
loop architecture
R programming language provides the following kinds of loop to handle looping requirements. Click the following links to check their detail.
Loop Type & Description
repeat loop
Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.
while loop
Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body.
for loop
Like a while statement, except that it tests the condition at the end of the loop body.

Loop Control Statements

Loop control statements are useful to change execution from its normal sequence. When execution leaves a scope, all automatic objects that were created in that scope are destroyed.
Here are some control statements supported by R language. Click the following links to check their detail.
Control Statement & Description
break statement
Terminates theloopstatement and transfers execution to the statement immediately following the loop.
Next statement
