我有一个带有一些全名的数据框和一个带名字的向量:
d <- data.frame(myName = c("Adam Smith","John Smith","John Clarks "))
first <- c("Adam","Mark","Jim")
我需要检查来自&#34; first&#34;包含在&#34; d&#34;的每一行中,因此结果应如下所示:
Adam Smith TRUE
John Smith FALSE
John Clarks FALSE
有人可以帮忙吗?

您可以使用grepl()
:
d <- data.frame(full_names = c("Adam Smith","John Smith","John Clarks "))
first <- c("Adam","Mark","Jim")
d$check <- grepl(paste0(first, collapse = "|"), d$full_names)
d
full_names check
1 Adam Smith TRUE
2 John Smith FALSE
3 John Clarks FALSE
