Hi there,
how can I test every element in a vector whether appears in another
vector?
such as
a<-c("aa", "bb", "ff", "cc")
b <-c("oo","jj","bb","cc")
somefunction(a,b) gives [False, True, False, True]
The other answers probably gave you what you wanted, but you should
not leave this exchange thinking that True == TRUE or that False
=FALSE in R.
