named arguments in functions r in r

In R, we can use named arguments in functions to make the code more readable and less prone to errors. Named arguments allow us to specify the parameter values for a function by name, instead of relying on their order.

To use named arguments, we can simply specify the parameter name followed by a = sign and the corresponding value. Here is an example:

main.r
# Define a function with named arguments
my_function <- function(a, b, c) {
  result <- a + b + c
  return(result)
}

# Call the function with named arguments
my_function(a = 1, c = 3, b = 2)

# Output: [1] 6

11 lines

In the example above, we defined a function called my_function with three parameters: a, b, and c. We then called the function with named arguments, specifying the value of a as 1, b as 2, and c as 3. The function returned the sum of the three parameters, which is 6.

Using named arguments can improve the readability of our code and make it easier to modify or adjust the parameters in the future without having to worry about their order in the parameter list.
