R Custom Functions: Complete Guide

To customize a function in R language, you can use the following syntax:

my_function <- function(arg1, arg2) {
  # Function body
  result <- arg1 + arg2
  return(result)
}

# 调用自定义函数
result <- my_function(3, 4)
print(result)

In the example above, we defined a function called my_function that takes two parameters, arg1 and arg2, adds them together, and returns the result. To call this function, simply provide the appropriate parameters and use my_function().
