在数据框中找到一系列规则，并带有中断规则

我展示了我如何看待这个算法的实现，我把它分为两个步骤

第一步序列搜索

第二步检查中断规则

set.seed(123)
dat <- as.data.frame(matrix(sample(10,60,replace = T),ncol = 3))
colnames(dat) <- LETTERS[1:ncol(dat)]
dat

rule <- c("A==0","A==10 & B==4","C==9","A>10","B<0","C==0","A==5","A>10",
          "B<0","C==0","A==9 & B==9","A>10","B<0","A==10","A==7 & B==5")
action <- c("break","next","next",rep("break",3),"next",rep("break",3),
            "next",rep("break",3) ,"next")

rule <- cbind(rule,action)
