Hi, I am new R user and I am still learn this fabulous software. I am stuck on this part. I need to check 2 character vectors v1 <- c("age_1","age_2","age_3","age_4","age_5","age_6","height_1","height_2","height_3","height_4","height_5","height_6","height_7","height_8")
and v2 <- c("sex_1","sex_2","sex_3","age_height_1_1","age_height_2_2","age_height_3_3","age_height_4_4","age_height_5_5","age_height_6_6", "age_height_1_7","age_height_2_8") what I really want to do is loop over v2 and check if its interaction component have any element in v1then return this component (i.e. v2 [4] = "age_height_1_1" then check v1 which has "age_1" or "height_1" then return "age_height_1_1") . Is there a way to do that?
