It is nothing but calling the original function with a valid number of argumentsA function can be called with or without argument and with a default value also.
We can easily call a function, we simply have to use the function’s name and provide arguments call. We can also call a function from anywhere in the environment in which the function is declared.
Syntax
function_name(arguments)Example
new.function <- function(a)
{
for(i in 1:a)
{
b <- i^2
print(b)
}
}
new.function(6)Output:
[1] 1 [1] 4 [1] 9 [1] 16 [1] 25 [1] 36
