Question

Write function in R language

Answer 1

In some occasion, we need to write our own function because we have to accomplish a particular task and no ready made function exists. A user-defined function involves a name, arguments and a body.

function.name <- function(arguments) 
{
    computations on the arguments	
    some other code
}		

Note: A good practice is to name a user-defined function different from a built-in function. It avoids confusion.
