I want to get a list of all the positions of entries in that vector that are in [2,6], so id like the output to be

2 3 4 5 8 9

please help

Try `which` (`?which`) – Vincent Guillemot Feb 29 '16 at 17:41 — Vincent Guillemot, Feb 29 '16 at 17:41
`a<-c(1,4,2,5,6,7,8,3,5);which(a %in% 2:6, arr.ind = T)` – Robin Gertenbach Feb 29 '16 at 17:42 — Robin Gertenbach, Feb 29 '16 at 17:42
