Thanks for help, but this does not solve my problem. As a simple example, lets assume we have a data set containing five 6's and five 7's. so the sample size is 10. Now if I wanted to keep the data values below the 75 th percentile, I would roughly have 7 observations remaining. However, following your suggestion I end up keeping all the observations.
