• first()
• highestAverage()
• highestCurrent()
• highestMax()
• last()
• lowestAverage()
• lowestCurrent()
• lowestMin()
• max()
• min()
• sample()
• top()
• unique()

The following functions can be used as both selectors or aggregates, but they are categorized as aggregate functions in this documentation:

• median
• quantile
