Hi, Try: vec1 <- setNames(c(0.1,0.2, 0.5, 0.1,0.8, 0.4, 0.9), 1:7) vec2 <- sort(vec1,decreasing=TRUE)
names(vec2[seq(ceiling(length(vec2)*0.3))]) #[1] "7" "5" "3" A.K. Hi, I need your help again. I have some data like this: 1 2 3 4 5 6 7 ... 0.1 0.2 0.5 0.1 0.8 0.4 0.9 ... I need to select the 30% higgest values,but in the ouitput I need the index (position where is the maximum values). In that case the output will be 7,5,3,... for example.
