Re: [R] choosing items from array: very stupid and simple question

This does literally what you asked for x[x %in% y] [1] 2 3 This is more likely what you want which(x %in% y) [1] 2 3 It is an artifact of this example that the two results look the same. Here is a different example that distinguishes them, and in this example, %in% is probably not right
