Dear all,  

I would like to take out the values from one vector that are equal to the values in another vector.  

Example:
a <- c(1,2,3,4,5,6,7,8,9)
b <- c(3,10,20,5,6)
b_noRepeats = c(10,20)

So I would like to have the vector b without the same values as vector a.    

Kind regards,
Joćo Fadista
