Extracting a range of values from a list, but excluding a few in R

If I have a vector with the integers from 1 to 100 and I want to extract the integers from 30 to 60 but not include 40 how do I do that? I can do each part on its own:

y<-1:100
y[30:60]
y[-40]

But I can't find a way to do both at once. How do I do that?

Note that I am NOT looking for a solution like this:

y[c(30:39,41:60)]

but instead, a solution that explicitly extracts the value I don't want.

Solution

  • Here is another base R option using %in% and &

    y[(u <- seq_along(y)) %in% 30:60 & u != 40]
