How to create quintile of variable in R

Question

Is it possible to bin a variable in to quintile (1/5th) using R. And select only the variables that fall in the 5th bin.

As of now I am using the closest option which is quartile (.75) as there is not a function to do quintile.

Any suggestions please.

`Hmisc::cut2()` with `g = 5` should to the trick. – m-dz Aug 05 '16 at 08:55 — m-dz, Aug 05 '16 at 08:55

Not completely sure what you mean, but this divides a dataset into 5 equal groups based on value and subsequently selects the fifth group

obs = rnorm(100)
qq = quantile(obs, probs = seq(0, 1, .2))
obs[obs >= qq[5]]
