Question

我有这段代码

> read.xlsx("Book1.xlsx", a[2])
Error in read.xlsx.default("Book1.xlsx", a[2]) : 
  Cannot find sheet named "S&P500 TR"

简单地说，我希望它在字符串写出正确的句子时停止循环随机值，在这种情况下它是“我爱你”。我需要添加什么才能使其停止，以便W1 [0] W2 [1]等。

如果重要的话，使用Processing来编写它。

这应该有用，但我从未使用过Processing，所以我不确定你的原始代码有多正确。

void draw() {
  //I love you sentance
  String[] W1 = { 
    "I", "love", "you", "."
  };
  String[] W2 = { 
    "I", "love", "you", "."
  };
  String[] W3 = { 
    "I", "love", "you", "."
  };
  String[] W4 = { 
    "I", "love", "you", "."
  };
  String Sentence = "";
  while (!Sentence.equals("I love you .")) {//the last space is required
      int w1 = int(random(W1.length));
      int w2 = int(random(W2.length));
      int w3 = int(random(W3.length));
      int w4 = int(random(W4.length));

      Sentence = W1[w1]+" "+W2[w2]+" "+W3[w3]+" "+W4[w4];
      println(Sentence);

      background(239,238,238);
      textAlign(CENTER);
      textFont(f);
      fill(66,134,244);
      text(Sentence, 0.5*displayWidth, 0.5*displayHeight+25);

      delay(1000);
  }
}

显示正确的值时停止随机字符串
