Constructors

LinqExtensions.DataFrameGrouping<TKey, R, C>

Constructs a new grouping object.

Properties

Key	Gets the key of the grouping.
Values	Gets a list of the values in the grouping.

Methods

Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
GetEnumerator	Returns an enumerator that iterates through the collection.
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
ToString	Returns a string that represents the current object. (Inherited from Object)

Extension Methods

Group<DataFrameRow<R, C>>	Returns a grouping by the unique elements in a sequence. (Defined by Grouping)
Group<DataFrameRow<R, C>>	Returns a grouping by the unique elements in a sequence using the specified comparer to determine equality. (Defined by Grouping)
Sum<DataFrameRow<R, C>>	Computes the sum of the sequence of values. (Defined by ArrayMath)
Sum<DataFrameRow<R, C>, U>	Computes the sum of the sequence of values that are obtained by invoking a transform function on each element of the input sequence. (Defined by ArrayMath)
