explorer 0.7.1

v0.7.1

on Hex

Added

• Add more temporal arithmetic operations. This change makes possible
  to mix some datatypes, like date, duration and scalar types like
  integers and floats.

  The following operations are possible now:

  • date - date
  • date + duration
  • date - duration
  • duration + date
  • duration * integer
  • duration * float
  • duration / integer
  • duration / float
  • integer * duration
  • float * duration

• Support lazy dataframes on Explorer.DataFrame.print/2.

• Add support for strings as the "indexes" of Explorer.Series.categorise/2.
  This makes possible to categorise a string series with a categories series.

• Introduce cond/1 support in queries, which enables multi-clause conditions.
  Example of usage:

      iex> df = DF.new(a: [10, 4, 6])
      iex> DF.mutate(df,
      ...>   b:
      ...>     cond do
      ...>       a > 9 -> "Exceptional"
      ...>       a > 5 -> "Passed"
      ...>       true -> "Failed"
      ...>     end
      ...> )
      #Explorer.DataFrame<
        Polars[3 x 2]
        a integer [10, 4, 6]
        b string ["Exceptional", "Failed", "Passed"]
      >
  

• Similar to cond/1, this version also introduces support for the if/2
  and unless/2 macros inside queries.

• Allow the usage of scalar booleans inside queries.

• Add Explorer.Series.replace/3 for string series.
  This enables the replacement of patterns inside string series.

Deprecated

• Deprecate Explorer.DataFrame.to_lazy/1 in favor of just lazy/1.

Fixed

• Fix the Explorer.Series.in/2 function to work with series of the
  :category dtype.

  Now, if both series shares the same categories, we can compare them.
  To make sure that a categorical series shares the same categories from
  another series, you must create that series using the
  Explorer.Series.categorise/2 function.

• Display the dtype of duration series correctly in Explorer.DataFrame.print/2.
