I have a two different vectors

v1 <- c("HelloWorld", "Climate","fooboo","testtesting")
v2 <- c("hello","test")

I want to compare both the vector and need to get "HelloWorld" and "testingtestin".

I used regexpr, but i have'nt get the result.

sapply(v1 , regexpr, v2 ,  ignore.case=TRUE)

try `grep(paste(v2, collapse = '|'), v1, ignore.case = TRUE, value = TRUE)` – Sotos Dec 27 '17 at 14:25

Or using `sapply` (OPs way): `sapply(v2, grep, v1, value = TRUE, ignore.case = TRUE)` – pogibas Dec 27 '17 at 14:26
