[R] elegant way to remove cases with many different ids

I have nested data with cases grouped by IDs and I want to remove all cases with specific IDs.
subset(df,id== 1 | id == 3)
Having a very large dataset with many IDs to remove this solution leaves me to write quite a long list of "id == x | id == y | id == z ...". I wonder if there is a more elegant way to do this? I tried with "id = c(x,y,z)" but this did not give the proper result.
Any suggestions? Thank you!
