How do I return two values in R?

The return() function can return only a single object. If we want to return multiple values in R, we can use a list (or other objects) and return it.

What is return mean in programming?

In computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after the instruction which called the subroutine, known as its return address.

Where is the return value of a function stored?

Where is it stored? Well, it isn’t stored. It actually gets erased from memory. When we call a function, the function executes its code and after the return, that particular function call gets wiped out from working memory ( the browser is in charge of the cleanup task).

Does a function always return a value?

Yes it always returns a value, if explicit one is not given, it returns undefined .

What is difference between Lapply and Sapply?

Difference between lapply() and sapply() functions: lapply() function displays the output as a list whereas sapply() function displays the output as a vector. lapply() and sapply() functions are used to perform some operations in a list of objects.

How do I return two outputs from a function in R?

What is the c () in R?

The c() is a built-in R generic function that combines its arguments. The c() in R is used to create a vector with explicitly providing values. The default method combines its arguments to form a vector. All arguments are coerced to a common type of the returned value, and all attributes except names are removed.

Can I return two values from a function?

No, you can not have two returns in a function, the first return will exit the function you will need to create an object.

What is double return type?

Data type double is larger than char, hence, double return type is large enough to hold a char value and return it from the method. There is no loss in the value of char even if its value is widened to a double.

What is the use of return value of and function?
