Writing if else statements in R

We often use if statements in MS Excel, but we can also write a small code to perform simple tasks in R.

How to do it…

The logic for if else statements is very simple and is as follows:

if(x>3){
  print("greater value")
}else {
  print("lesser value")
}

We can copy and paste the preceding statement in the R console or write a function that makes use of the if else logic.

How it works…

The logic behind if else statements is very simple. The following lines clearly state the logic:

if(condition){
#perform some action
}else {
  #perform some other action
}

The preceding code will check whether x is greater than or less than 3, and simply print it. In order to get the value, we type the following in the R command window:

x = 2
