Libraries.Compute.Statistics.DataFrameSelection Documentation

This encompasses the overall selection of columns and factors in the DataFrame. DataFrame, by default, passes through all of its actions into this system. The selection itself is more rigid than the DataFrame, on purpose, so that the potential points of failure exist only in one place.

Actions Documentation

Add(Libraries.Compute.Statistics.DataFrameSelectionListener listener)

Parameters

AddCell(Libraries.Containers.Support.Pair<integer> cell)

Parameters

AddCell(integer x, integer y)

Parameters

  • integer x
  • integer y

AddColumn(integer column)

Parameters

  • integer column

AddFactor(integer column)

Parameters

  • integer column

AddRow(integer row)

Parameters

  • integer row

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

CopyTo(Libraries.Compute.Statistics.Inputs.CellInput col)

Parameters

CopyTo(Libraries.Compute.Statistics.Inputs.RowInput col)

Parameters

CopyTo(Libraries.Compute.Statistics.Inputs.FactorInput col)

Parameters

CopyTo(Libraries.Compute.Statistics.Inputs.ColumnInput col)

Parameters

EmptyCells()

EmptyColumns()

EmptyFactors()

EmptyRows()

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
