Dear R-users, I'd like to turn a vector so it starts with it's end. For better understanding, this set of commands will do what I need: i <- seq(1:10) i_turned <- i for (j in 1:length(i)) i_turned[j] <- i[length(i)-j+1] now, i_turned is what I call turned. Is there a function which would make a script lighter? Thank you upfront for any hint. Best regards, Zroutik [[alternative HTML version deleted]]
