R if...else Statement We can also use an optional else statement with an if statement. The syntax of an if...else statement is: if (test_expression) { # body of if statement } else { # body of else statement }
If the condition statements associated with else if block evaluated to return a TRUE boolean value, R process the code available inside the else if block. However, if the condition of else it returns a FALSE boolean value, R ignores the code and checks for next else if statement. If it f...
In this tutorial, we will learn what control statements in R programming are, and its types. Here, we will discuss If, If- Else and for loop in R programming.
5 Loops and if/else statements in R In R programming, the order of statements in which they are written is very important. A program is executed statement by statement (line after line from up to down) in a sequence. This flow of execution may be considered as the normal flow. But in...

In this example we use two variables, a and b, which are used as a part of the if statement to test whether b is greater than a. As a is 33, and b is 200, we know that 200 is greater than 33, and so we print to screen that "b is greater than a"....
Now that we’ve added an if-else statement, let’s look at how to stop a for loop based on a certain condition. In our case, we can use abreakstatement to stop the loop as soon as we see Team A has won a game. Using the for loop we wrote above, we can insert the break sta...
Control Structures: if if(<condition>){ ## do something } else{ ## do something else } if(<condition1>){ ## do something }else if(<condition2>) { ## do something different }else { ## do something different } 例: if(x> 3) { ...

The basicconditional statementuses an if-else structure. This might be best explained by example. Suppose we want to enter a value,x, and have R reply with “small” ifx≤ 3 and with “big” ifx> 3. We can type if ( x <= 3 ) {# if x is less than or equal to 3 ...
