如何在 R 中编写不等式

Question

Sorry, I am an R newbie and I am having some difficulty抱歉，我是 R 新手，我遇到了一些困难

How would I write the following inequality in R:我将如何在 R 中编写以下不等式：

x > 10 is twice more likely than x < 10 x > 10 的可能性是 x < 10 的两倍

I tried this function and it didn't work:我试过这个 function 但没有用：

X = 10 

f = function(X,Y) { 
  if ((2(X) >= 10 & X <= 10) { 
    print("in range") 
  } else {
    print("out of range") 
  } 
}

Answer 1

Your code has a syntax error if that's the problem:如果这是问题所在，您的代码有语法错误：

X = 10 
f = function(X,Y) {
  if (2 * X  >= 10 && X <= 10) {  # * instead of (
    print("in range") 
  } else { 
    print("out of range") 
  } 
}

You can try your function as in:您可以尝试您的 function，如下所示：

 > f(10,10) [1] "in range" > f(20,10) [1] "out of range"
