We can use match %in% to check whether a vector contains a given value of not

Example

> x <-c(1,10, 99, 1024)
> 1%in%x
[1] TRUE
> 10%in%x
[1] TRUE
> 99%in%x
[1] TRUE
> 1024%in%x
[1] TRUE
> 100%in%x
[1] FALSE

We can also do this for checking the common values between two vectors.

Example

> x <-c(1,10, 99, 1024)
> y<-c(2,10, 133, 1000)
> x%in%y
[1] FALSE TRUE FALSE FALSE
