Explanation:

This is a user defined function using R programming Language. Another way to do that. 
hello.person <- function(firstName, lastName)
{
  print(sprintf("Hello %s %s", firstName, lastName))
}

hello.person("Rumman", "Ansari")

hello.person(lastName = "Ansari", firstName = "Rumman")

If you will run the above program you will get the following result

> hello.person("Rumman", "Ansari")
[1] "Hello Rumman Ansari"
> hello.person(lastName = "Ansari", firstName = "Rumman")
[1] "Hello Rumman Ansari"
