Look at ?agrep:
Vec1 <- "What a nice day today! - Story of happiness: Part 2."
Vec2 <- "What a nice day today: Story of happiness (Part 2)”
# Match the words, not the punctuation.
# Not fully tested
> agrep("What a nice day today Story of happiness Part 2", c(Vec1, Vec2))
[1] 1 2
> agrep("What a nice day today Story of happiness Part 2", c(Vec1, Vec2),
value = TRUE)
[1] "What a nice day today! - Story of happiness: Part 2."
[2] "What a nice day today: Story of happiness (Part 2)”
