v0.42.0

Documentation:

  • Many JavaDoc additions and extensions.
  • Update documentation readme to include all project javadoc links (#1022)

Enhancements

  • Wrap IOException for file reads (#1021). IOException is caught and re-thrown wrapped in a runtime exception RuntimeIOException. For interactive work, this greatly reduces the number of exceptions that need to be caught. Writes will handled in the next release.
  • Cleanup on aggregate function names (#1020). Abstract AggregateFunctions were given a consistent name structures. All class names now have the form: [columnType][returnType]AggregateFunction (e.g. BooleanIntAggregateFunction). If the column and return type are the same, it is not repeated (e.g. StringAggregateFunction).
  • Some aggregate function classes were made public so library users can subclass
  • A few methods were added to Column subclasses. Notably, an asSet() method was added to columns where it was not already present.
  • improved error message for Column append methods (#1019)

v0.40.0

This release focused on minor enhancements that eliminate gaps in functionality.

Note that the change to method Table:shape() modified the String that is returned, changing the functionality of the method slightly.

Enhancements

@lwhite1 Minor extensions (#999) Added methods:

  • DoubleColumn:asDoubleArray()

  • FloatColumn:asFloatArray()

  • IntColumn:asIntArray()

  • ShortColumn:asShortArray()

  • StringFilters:isIn()

  • StringFilters:iNotIn()

  • IntColumn:isNotIn()

Other enhancement:

  • Made Table:append() accept any Relation as its argument, not just another table.

Made Table:removeColumns() return Table rather than Relation (#1003) …

Added method Date:isNotEqualTo(LocalDate) (#1004) …

Made shape() return the name of the table, along with the shape (#1005)

Standardized names for methods, added missing methods (#1010)

  • Deprecated addRow(Row) and added appendRow(Row) to make the name more consistent with append(Table).
  • Added methods selectColumns() and rejectColumns() to provide variations to removeColumns() and retainColumns() that return new tables rather than modify the table in-place.
  • Added method Relation:containsColumn(String name);
  • other minor enhancements to code and documentation

Made Table:countBy() take varargs so the counts can group on more than one column

V0.38.4

This is a relatively small release with a few nice enhancements and several bug fixes. There is also a documentation enhancement publicizing @ccleva's Parquet integration project.

Bug fixes

Fix bug where missing values in numeric columns could not be formatted. This enables arbitrary missing value indicators (e.g. "N/A") to be used in printing and saving to files. @lwhite1

Replace parallelQuickSort with mergeSort (#968), to avoid incorrect sorting caused by race conditions when a custom sort object is used. @lwhite1

fix issue #963 (#967) Relation.structure() fails for TableSlice with ClassCastException @lwhite1

Enhancements

Aggregate by non-primitive column type that extends Number (#973), making it possible to add a column type for BigDecimal @daugasauron @kallur

plotly - added range slider to Axis (#953) … @smpawlowski

To support annotation in plot.ly javascript. (#944) … @xcjusuih

Documentation

Added link to the tablesaw-parquet project in README (#966) @ccleva
