Question

我正在运行一个if if else阶梯，它应根据随机生成的变量（enctypef[1,1]）从一系列表中进行选择，并在其中生成一个随机样本。

我对以这种方式使用R很陌生，并且使用switch函数也不能解决问题。将if else放在方括号中也可以避免R问题出现在不同的行上。（这是为了产生地下城与龙日的旅行发电机。）

{
  if (enctypef[1,1] = 1) {
    print(charaenc[sample(nrow(charaenc),1, replace= TRUE), ])
} else if (enctypef[1,1] = 2) {
    print(fsocenc[sample(nrow(fsocenc),1, replace= TRUE), ])
} else if (enctypef[1,1] = 3) {
    print(hsocenc[sample(nrow(hsocenc),1, replace= TRUE), ])
} else if (enctypef[1,1] = 4) {
    print(skllchall[sample(nrow(skllchll),1, replace= TRUE), ])
} else if (enctypef[1,1] = 5) {
    print("Combat! (Non-commital)")
} else
print("Combat! (Aggressive!)")
}

我希望基于遇到类型为1：6的随机样本，它将在4个可用表上滚动或打印“ Combat！（Non-commital）” / Combat！（非承诺）。

我得到的错误如下：

否则，如果梯子无法从给定的选项中进行选择
