Different Types of Functions in Rĭifferent R functions with Syntax and examples (Built-in, Math, statistical, etc.) 1. Second, return (): Inside the function, we have a return (), which causes our function to exit and hand back value to its caller. I will be explaining these terms in detail:įirst, Parameters: These are the variables on which we perform the operation defined in the Function. Now, we have come across a few new terms like return (), and after the name of the function, we have passed two values x, y these are termed as parameters. The highlighted lines are termed as the body of the function. Suppose we have to calculate the sum of two numbers:
#Random number loop in r code#
The code of the function is closed under curly braces. We write the steps to perform certain operations these steps are termed as the body of the function. It’s better to give the name “Sum “ to that function. We can give any name to our function, but we decide the function name based on theįunctionality, i.e., the type of operation it performing.įor example, if we are creating a function to calculate the sum of 2 numbers, then. Here I am explaining each component of this user-defined function. Here is the format for writing our own function: Here if someone wants, arguments can also be set to the default value. As you can see, we have called the function by the name “Multi”. The first argument is x, and the second argument is y. Here we created the function name “Multi”, which takes two arguments as inputs and provides the multiplied output. Print(paste(x,"Multiply", y, "is", result)) Let’s see an example, which will be more lucid in understanding the concept. “Fun_name” is the name given to the function, through which it can be called anywhere in the R program. The function body is a set of logical statements that are performed over arguments, and then it returns the output. The function takes input which is in the form of arguments. Here, one can see “function” specific reserved word is used in R to define any function. Hadoop, Data Science, Statistics & others
