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
- Libraries.Language.Object: The object to compare to.
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
- Libraries.Language.Object: The to be compared.
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
- Libraries.Compute.Statistics.DataFrame: The DataFrame to copy and adjust
Return
Libraries.Compute.Statistics.DataFrame: Typically a copy of the DataFrame, transformed by the transformer.
