See this discussion for a variety of solutions.

So c(1,4,6) is accepted as a subvector of c(2,1,1,4,6,3), but not of
c(2,1,1,6,4,3).
How to test this?
How about this:
--- code ---
g1<- c(2,1,1,4,6,3)
g2<- c(2,1,1,6,4
Sorry. I should have mentioned that the order of the components is important.
So c(1,4,6) is accepted as a subvector of c(2,1,1,4,6,3), but not of
c(2,1,1,6,4,3).
How to test this?

Hi,
Try this:
Not sure whether this is the fastest:
set.seed(932)
vec1<-sample(1:10,6,replace=TRUE)
vec2<-sample(1:7,3,replace=TRUE)
vec2[vec2%in%vec1]
#[1] 5
library(rbenchmark)
benchmark(isTRUE(all(vec2%in%vec1)),replications=1e4)
# test replications elapsed relative us
