上表存储了第一列中前一个数据集中的汽车，下一列中我们有两个数字：0或1。我想在第一个数据中添加新列，指示第一列中的汽车是否为Porsche_1（全名是否重要。我的意思是_）和来自第二列的汽车{{1数据集编号为2的同一列中的数字为1.这不正确，因此我们在此附加列中放入0或NA。如果两者都在Astra_3和Porsche_1的同一列中排名第一 - 则应将数字1放入附加列中。

Desired out：最后一列的数字是随机生成的！

Astra_1

Answer 1

实现这一目标的一种方法是使用mapply并检查在X中具有第一个汽车名称的行中是否有1 tbl_test2（第一列除外）是对于包含X中第二个汽车名称的行（也就是检查是否为1列，我们有any），您还会TRUE & TRUE或{{TRUE每对1}}，然后您可以使用FALSE转换为0/1：

as.integer

修改

如果您想知道匹配的列号，可以使用：

tbl_test1$Comp <- mapply(function(x, y) as.integer(any(unlist(tbl_test2[tbl_test2$X==x, -1]) & unlist(tbl_test2[tbl_test2$X==y, -1]))), x=as.character(tbl_test1$X1), y=as.character(tbl_test1$X2)) head(tbl_test1) # X1 X2 AUC_1 AUC_2 ratio Country Comp #1 Porsche_1 Astra_3 5860133.702 4.849720e+06 1.2083447 France 0 #2 Mazda_2 Astra_4 1296009.939 9.289805e+05 1.3950885 France 0 #3 Tico_1 Mercedes_1 333123.493 3.205476e+05 1.0392325 Germany 1 #4 Nexia_1 BMW_1 250348.941 2.232872e+05 1.1211970 Italy 0 #5 Astra_1 BMW_2 1376193.334 1.340641e+06 1.0265187 Poland 0 #6 Astra_2 Porsche_1 4080502.863 4.720330e+06 0.8644529 Poland 0

Answer 2

使用dplyr，您可以按行计算第二个data.frame中与1中的名称对应的行的匹配X1的数量X2，然后查找是否至少有一个匹配项：

library(dplyr)
tbl_test1 %>% rowwise() %>% 
  mutate(nmatch = sum(which(tbl_test2[grep(X1, tbl_test2$X),]==1) 
                      %in% which(tbl_test2[grep(X2, tbl_test2$X),]==1)),
         Comp = as.integer(nmatch!=0))

#            X1         X2      AUC_1       AUC_2     ratio Country nmatch  Comp
#        (fctr)     (fctr)      (dbl)       (dbl)     (dbl)  (fctr)  (int) (int)

# ..        ...        ...        ...         ...       ...     ...    ...   ...

注意： nmatch列只是一个奖励，你可以一步到位，当然只有Comp。
