look at setdiff(), e.g.,

setdiff(b, a)

I hope it helps.

Best,

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
