How to check if a vector contains a given value in R?

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
