Libraries.Compute.Statistics.Transforms.ConvertColumnsToRanksTransform Documentation

This action takes the data from the current DataFrame then reverses it so that the top row is now at the bottom and vice versa.

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Transforms.ReverseTransform
    use Libraries.System.File

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

    //reverse the data frame
    ReverseTransform reverse
    frame:Transform(reverse)

Actions Documentation

AddColumn(integer column)

This action adds a value to the end of the input.

Parameters

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.

CreatesCopy()

This action tells us whether or not this transform makes a copy of the data or modifies it in place. Transforms that do not make a copy should override this action.

Example Code

use Libraries.Compute.Statistics.DataFrame
        use Libraries.Compute.Statistics.Transforms.ReverseTransform
        use Libraries.System.File

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

        //reverse the data frame
        ReverseTransform reverse
        output reverse:CreatesCopy() // by default, this transform returns true.

Return

boolean: True if this transform makes a copy.

EmptyColumns()

This action empty's the list, clearing out all of the items contained within it.

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.

GetColumn(integer index)

This action gets the item at a given location in an array.

Parameters

Return

integer: The item at the given location.

GetColumnIterator()

This action gets an iterator for the object and returns that iterator.

Return

Libraries.Containers.Iterator: Returns the iterator for an object.

GetColumnSize()

This action gets the size of the array.

Return

integer:

GetCompareValues()

This action takes the data from the current DataFrame then reverses it so that the top row is now at the bottom and vice versa.

Example Code

use Libraries.Compute.Statistics.DataFrame
        use Libraries.Compute.Statistics.Transforms.ReverseTransform
        use Libraries.System.File

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

        //reverse the data frame
        ReverseTransform reverse
        frame:Transform(reverse)

Return

boolean: Typically a copy of the DataFrame, transformed by the transformer.

GetFirstRank()

Return

integer

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.

GetSortSmallToLarge()

Return

boolean

IsEmptyColumns()

This action returns a boolean value, true if the container is empty and false if it contains any items.

Return

boolean: Returns true when the container is empty and false when it is not.

RemoveColumn(integer column)

This action removes the first occurrence of an item that is found in the Addable object.

Parameters

Return

boolean: Returns true if the item was removed and false if it was not removed.

RemoveColumnAt(integer index)

This action removes an item from an indexed object and returns that item.

Parameters

SetCompareValues(boolean compareValues)

Parameters

SetFirstRank(integer firstRank)

Parameters

SetSortSmallToLarge(boolean sortSmallToLarge)

Parameters

Transform(Libraries.Compute.Statistics.DataFrame frame)

This action takes the data from the current DataFrame then reverses it so that the top row is now at the bottom and vice versa.

Example Code

use Libraries.Compute.Statistics.DataFrame
        use Libraries.Compute.Statistics.Transforms.ReverseTransform
        use Libraries.System.File

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

        //reverse the data frame
        ReverseTransform reverse
        frame:Transform(reverse)

Parameters

Return

Libraries.Compute.Statistics.DataFrame: Typically a copy of the DataFrame, transformed by the transformer.
