below is a minimal reproducible example:
v=c("\\<skill-saw\\>","\\<saw blade\\>")
text="xx placed his hand beneath skill-saw blade"
sapply(v,grepl,text)
The last command returns c(TRUE,TRUE) where I was expecting c(TRUE,FALSE). Any idea on how to achieve that? The idea is that the keyword "skill-saw" should be detected as present in the text, but not the keyword "saw blade"...
Thanks a lot in advance for your help!
You can try regex
lookbehind
v <- c('(?<= )\\bskill-saw\\b', '(?<= )\\bsaw blade\\b')
unname(sapply(v, grepl, text, perl=TRUE))
#[1] TRUE FALSE
Based on the new "text", may be
text1 <- "xx placed his hand beneath skill saw-blade"
v <- c('(?<= )\\bskill-saw\\b', '(?<= )\\bsaw-?blade\\b')
unname(sapply(v, grepl, text1, perl=TRUE))
#[1] FALSE TRUE
