Libraries.Compute.Statistics.Loaders.CommaSeparatedLoader Documentation

This class can load data into a DataFrame from a comma separated value file. By default, this class chooses its columns from the first value in a cell.

Example Code

use Libraries.Compute.Statistics.DataFrame

    //Load a comma separated file
    DataFrame frame
    CommaSeparatedLoader loader
    File file
    file:SetPath("Data.csv")
    frame:Load(file, loader)

Actions Documentation

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.

Example Code

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

Parameters

Return

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

Equals(Libraries.Language.Object object)

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

Example Code

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

Parameters

Return

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

GenerateColumnFromText(text value)

Parameters

Return

Libraries.Compute.Statistics.DataFrameColumn

GetHashCode()

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

Return

integer: The integer hash code of the object.
