r - How to compare 2 vectors element by element using loop -


i'm trying compare elements 2 vectors in way,but result first element.

      >ex1<-c('gdgdg','dd','fffff','ssdsds')        fuct1<-function(x){         for(i in 1:length(x)){           ex2<-c('xxxx','ddd','ddd','ddd','dddd')           match<-agrep(x[i],ex2[i],value='true')           return(match[i])          }       }        >fuct1(ex1)

by example want compare 'gdgdg' , 'xxxx'(first elements each vector) 'dd'and 'ddd'(second ones) , on...,as result have (na,ddd,na,na). result code na. help.

t think looking mapply

  mapply(agrep,ex1,ex2,value=true)

but assume 2 vectors have same length.
