如何从字符串中提取 group/list 个单词中包含的单词？
How do I extract a word, that is contained in a group/list of words, from a string?
来自字符串的字符向量
x <- c("Point to Point Movement, Route/Network Building",
"Betting/Wagering, Dice Rolling, Roll / Spin and Move",
"Hand Management, Take That")
提取包含在
中的单词
p <- c("Route","Dice")
否则NA。生成的输出将是来自 x[1] 的“Route”、来自 x[2] 的“Dice”和来自 x[3].
的 NA
将单词粘贴为单个字符串并在 str_extract
中使用
library(stringr)
str_extract(x, str_c(p, collapse="|"))
[1] "Route" "Dice" NA
