How to extract element from vector that contained substring from another vector in R?

Question

Given:

V1 <- c("abcd", "efgh", "ijkl", "mnop", "qrst")
V2 <- c("ab", "fg", "op")

Is there a R function to get

V3 <- string_fxn(V1, V2)

Such that

V3 = c("abcd", "efgh", "mnop")

An option is grep from base R

grep(paste(V2, collapse="|"), V1, value = TRUE)
#[1] "abcd" "efgh" "mnop"
