[R] Is variable in one vector part of variable in another

[Philipp Pagel]

> I have 2 vectors x & z
> x  has 10 variables in it
> z has 75 variable in it
> 
> I need to check all 75 variables in z and see if they are present in the
> vector x.

In addition to the solution using %in% which has already been suggested,
you may also want to play with something like this:

# make up some data
x = sample(1:8, 10, rep=T)
z = sample(1:25, 75, rep=T)
# find intersection between x and z
intersect(x,z)
