Unused Argument

Will R ignore the unused arguments?

in R is it possible to ignore the unused arguments, for example, I have a module add(x,y) which returns the sum of x and y but the code is.

add(x=10, y=30, c=5)

It returns an error.

To avoid the error you can simply add dots in the function definition just like this:

 add <- function(x, y, ...){ 

cat(x,y) }

 myfun(x=4,y=7,hello=3)
