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
frame:Load(file, loader)

Inherits from: Libraries.Compute.Statistics.DataFrameLoader, Libraries.Language.Object

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.



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


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

Equals(Libraries.Language.Object object)

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



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


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

GenerateColumnFromText(text value)

By default, if the first row is an NA value, or text, a text column is used. If the first column can be interpreted as a number, a NumberColumn is used. Integer columns are never prioritized as a default, although non-numbers can be interpreted as booleans given text input in a first row.


  • text value




This action gets the hash code for an object.


integer: The integer hash code of the object.


Object o
integer hash = o:GetHashCode()
