The Subset type exposes the following members.
Top
| Name | Description |
---|
 | EndIndex |
Gets the index of the observation past the last visible observation.
|
 | IsContiguous |
Gets whether the subset selects a contiguous range
which may wrap around the end of the collection.
|
 | IsEmpty |
Gets whether the subset is empty.
|
 | IsSlice |
Gets whether the subset selects a contiguous range.
|
 | Item |
Gets the position of the observation at the specified index.
|
 | Length |
Gets the number of elements in the subset.
|
 | OriginalLength |
Gets the length of the original data.
|
 | StartIndex |
Gets the index of the first visible observation.

| Name | Description |

 | ApplySort |
Returns a subset that applies the specified sort subset to the current subset.
|
  | Complement |
Returns a Subset that is the complement of the specified subset.
|
 | 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 over the indexes in the subset.
|
 | GetHashCode | Serves as the default hash function. (Inherited from Object.) |
 | GetReverse |
Returns a subset that lists the observations of the current subset
in reverse order.
|
 | GetType | Gets the Type of the current instance. (Inherited from Object.) |
  | Intersection |
Returns a subset representing the intersection of two subsets.
|
 | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
  | Reverse |
Returns a subset that reverses the observations.
|
 | ToString | Returns a string that represents the current object. (Inherited from Object.) |
  | Union |
Returns a subset that represents the union of two subsets.

 | GroupInt32 | Overloaded.
Returns a grouping by the unique elements in a sequence.
(Defined by Grouping.) |
 | GroupInt32(IEqualityComparerInt32) | Overloaded.
Returns a grouping by the unique elements in a sequence
using the specified comparer to determine equality.
(Defined by Grouping.) |
 | SumInt32 | Overloaded.
Computes the sum of the sequence of values.
(Defined by ArrayMath.) |
 | SumInt32, U(FuncInt32, U) | Overloaded.
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.) |

Use the Subset object to select a subset of the elements
in a VectorT or the rows in a IDataFrame.
