Subject: [SPAM?] [R] Remove vector elements from another vector


Hello,

I have two vectors of different lengths. Fx a <- 1:9; b <- c(4, 5).
What is the best way to remove the elements in vector b from vector a 
so
that the result would be a vector with elements c(1,2,3,6,7,8,9)?

Best regards,
Kalle
