If this
If statements are great for adding extra logical flow to your code. First, let's look at the basic structure of an if statement:
if(condition) {
code
}
The condition is anything that returns a single TRUE or FALSE. If the condition is TRUE, then the code inside gets executed. Otherwise, the code gets skipped and the program continues. Here is an example:
apple <- 54.3
if(apple < 70) {
print("Apple is less than 70")
}
[1] "Apple is less than 70"
Relational operators are a common way to create the condition in the if statement! The variable, micr, has been created for you.
