# Call the function new.function supplying 6 as an argument. new.function(6) 当我们上面的代码执行时,它产生以下结果: [1] 1 [1] 4 [1] 9 [1] 16 [1] 25 [1] 36 调用函数不带参数 # Create a function without an argument. new.function <- function() { for(i in 1:5) { print(i...
但是我们也可以通过提供参数的新值来获得非默认结果来调用这样的函数。 # Create a function with arguments. new.function <- function(a = 3, b = 6) { result <- a * b print(result) } # Call the function without giving any argument. new.function() # Call the function with giving new valu...
When a function is created then the user needs to take a look over the different parameters that eventually give rise to the well-structured function in a program. The following are the prime parameters that need to exemplify while working with the creation of a function in the program concern...
function_name <- function(arg_1, arg_2, ...) { Function body } 函数组件 函数的不同部分 - 函数名称 -这是函数的实际名称。它作为具有此名称的对象存储在 R 环境中。参数 -参数是⼀个占位符。当函数被调⽤时，你传递⼀个值到参数。参数是可选的; 也就是说，⼀个函数可能不包含参数。参数也...
