我有一个包含“地址”，“区域”和“州”的数据帧（df）为三列：
输入：
Address District State
132, 1st block, Mysore,Karnataka Mysore Karnataka
24, 4th Block, Jayanagar India Bangalore Karnataka
Prestige owen, M.G Road Bangalore Karnataka
Opp: Reliance trend, Mantri Mall,-Delhi New Delhi New Delhi
基本上我想标记（作为新列）“地址”栏下“实体”栏下的实体所在的行，
预期产出：
Address District State Dist_match
132, 1st block, Mysore,Karnataka Mysore Karnataka TRUE
24, 4th Block, Jayanagar India Bangalore Karnataka FALSE
Prestige owen, M.G Road Bangalore Karnataka FALSE
Opp: Reliance trend,
Mantri Mall,-Delhi New Delhi New Delhi TRUE
我尝试了以下但是收到了警告并且效果不佳
df$Dist_match <- mapply(grepl, pattern=df$District, x=df$Address)
