    Saddle is a Scala Data Library.

    Saddle

    Saddle is a Scala Data Library.

    Saddle provides array-backed, indexed one- and two-dimensional data structures.

    These data structures are specialized on JVM primitives. With them one can often avoid the overhead of boxing and unboxing.

    Basic operations also aim to be robust to missing values (NA's)

    The building blocks are intended to be easily composed.

    The foundational building blocks are:

    Inspiration for Saddle comes from many sources, including the R programming language, the pandas data analysis library for Python, and the Scala collections library.
