You can use the union() function to find the union of two vectors. To find the intersection of two vectors, use the intersect() function.

Here is an example:

x <- c(10,20,30,40,50,60)
y <- c(10,200,300,40,500,60)
intersect(x,y)
union(x,y)

The output of the above code will be:

> intersect(x,y)
[1] 10 40 60
> union(x,y)
[1]  10  20  30  40  50  60 200 300 500
