explorer 0.5.7

v0.5.7

on Hex

Changes

Added

• Allow Explorer.Series.select/3 to receive series of size 1 in both sides.

• Add trigonometric functions sin/1, cos/1, tan/1, asin/1, acos/1 and
  atan/1 to Explorer.Series.

• Add Explorer.DataFrame.to_rows_stream/2 function. This is useful to traverse
  dataframes with large series, but is not recommended since it can be an expensive
  operation.

• Add LazyFrame version of Explorer.DataFrame.to_ipc/3.

• Add options to control streaming when writing lazy dataframes. Now users can
  toggle streaming for the to_ipc/3 and to_parquet/3 functions.

• Add Explorer.DataFrame.from_ipc_stream/2 lazy, but using the eager implementation
  underneath.

• Add option to control the end of line (EOF) char when reading CSV files.
  We call this new option :eol_delimiter, and it's available for the from_csv/2
  and load_csv/2 functions in the Explorer.DataFrame module.

• Allow Explorer.DataFrame.pivot_wider/4 to use category fields.

Fixed

• Fix nif_not_loaded error when Explorer.Series.ewm_mean/2 is called from query.

• Type check arguments for boolean series operations, only allowing series of
  the boolean dtype.

• Do not use ../0 in order to keep compatible with Elixir 1.13

Removed

• Temporarely remove support for ARM 32 bits computers in the precompilation
  workflow.
