Deleting rows given a conditional vector - R [duplicate]

Given this df:

   A B  C
1  a 1 53
2  a 0 27
3  a 1 46
4  b 1 42
5  c 0 97
6  d 1 46
7  d 0 24

And the values defined to match for deleting are in a vector:

values_delete <- c("b", "c")

How can I delete the rows in df using a conditional with the vector? I tried:

df2 <- df[df$A != values_delete,]

But it doesn't allow it. This is the error:

longer object length is not a multiple of shorter object lengthlonger object length is not a multiple of shorter object length
