Libraries.Compute.Statistics.Loaders.CommaSeparatedSaver 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
use Libraries.Compute.Statistics.Loaders.CommaSeparatedSaver
use Libraries.System.File

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

//this would override itself
CommaSeparatedSaver saver
saver:Save(frame, file)

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

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.

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)

ConvertToText(Libraries.Compute.Statistics.DataFrame frame, integer rows)

This action can convert a data from to a Comma separated value text.

Parameters

Return

text:

Example


    use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Loaders.CommaSeparatedSaver
    use Libraries.System.File

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

    CommaSeparatedSaver saver
    text value = saver:ConvertToText(frame)
    output value

ConvertToText(Libraries.Compute.Statistics.DataFrame frame)

This action can convert a data from to a Comma separated value text.

Parameters

Return

text:

Example


    use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Loaders.CommaSeparatedSaver
    use Libraries.System.File

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

    CommaSeparatedSaver saver
    text value = saver:ConvertToText(frame)
    output value

ConvertToText(Libraries.Compute.Statistics.DataFrame frame, integer rows, boolean showHeader)

This action can convert a data from to a Comma separated value text.

Parameters

Return

text:

Example


    use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Loaders.CommaSeparatedSaver
    use Libraries.System.File

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

    CommaSeparatedSaver saver
    text value = saver:ConvertToText(frame, 3) //three rows
    output value

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)

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

Save(Libraries.Compute.Statistics.DataFrame frame, Libraries.System.File file)
