找到与R匹配的最佳字符串

2023年1月8日 201次阅读

从这个L Hernandez开始

从包含以下内容的向量：

[1] "HernandezOlaf "    "HernandezLuciano " "HernandezAdrian "

我试过这个：

'subset(ABC, str_detect(ABC, "L Hernandez") == TRUE)'

包括首都L anyplace的Hernandez这个名字是理想的输出.

期望的输出是HernandezLuciano

最佳答案 可能有帮助：

vec1 <- c("L Hernandez", "HernandezOlaf ","HernandezLuciano ", "HernandezAdrian ")
grep("L ?Hernandez|Hernandez ?L",vec1,value=T)
#[1] "L Hernandez" "HernandezLuciano "

更新

variable <- "L Hernandez"

v1 <- gsub(" ", " ?", variable) #replace space with a space and question mark 
v2 <- gsub("([[:alpha:]]+) ([[:alpha:]]+)", "\\2 ?\\1", variable) #reverse the order of words in the string and add question mark

您还可以使用strsplit将变量拆分为@rawr注释

grep(paste(v1,v2, sep="|"), vec1,value=T)
#[1] "L Hernandez"       "HernandezLuciano "
