Dear R-users, a very easy one for you, I guess. I need to extract the indexes of the elements corresponding to different quantiles of a vector. When a quantile is an interpolation between two adjacent values, I need the index of the value which is closer (the lower value - or the higher value for what matters - in case the quantile is exactly half way through).
This is an example. > x <- c(9,9,1,3,2,7,6,10,5,6) > quantile(x) 0% 25% 50% 75% 100% 1.0 3.5 6.0 8.5 10.0 What I need is a vector 'index' which looks like > index 3 4 7 1 8 Many thanks for your help !
