   The previous examples were always looking for an exact key. If we have an ordered
   series, we can search for a nearest available key and we can also perform slicing.

  In this section, we look at various features of the F# data frame library (using both
  `Series` and `Frame` types and modules). Feel free to jump to the section you are interested
  in, but note that some sections refer back to values built in "Creating & loading".
  
  You can also get this page as an [F# script file](https://github.com/BlueMountainCapital/FSharp.DataFrame/blob/master/samples/features.fsx)
  from GitHub and run the samples interactively.
