Note on queryPercentile()

lindbrook 2026-03-11

Due to the discrete nature of counts, your choice of percentile may not be available. This is because they may fall in the vertical gaps in the observed data:

For this reason, queryPercentile() rounds your selection to whole numbers. Also, be aware that the default value, which is set to 50, uses median()to guarantee a result.

head(queryPercentile())

You can also set a range of percentile ranks using the ‘lo’ and/or ‘hi’ arguments. If you get an error message, you may need to widen your interval:

head(queryPercentile(lo = 95, hi = 96), 3)
tail(queryPercentile(lo = 95, hi = 96), 3)
