I know how to find quantile of an empirical distribution.
set.seed(1)
x = rnorm(100)
q = quantile(x, prob=seq(0,1,.01))
Is there a function that would give me the quantile bin a number of the training set belongs to ? In this example
R) x[1]
[1] -0.6264538107
R) q

it would be quantile 18 (or 19 depending how you see things)
