Methods

AggregateInto<T, U>(Vector<T>, Aggregator<T, U>, Vector<U>) Aggregates the specified vector over each group and returns the result.
(Inherited from IGrouping)
AggregateInto<T, U>(Vector<T>, Vector<T>, Aggregator2<T, U>, Vector<U>) Aggregates the specified vector over each group and returns the result.
(Inherited from IGrouping)
Append Appends a vector at the end of this vector and returns the result.
(Inherited from IVector)
AppendMissingValues Appends the specified number of missing values to this vector and returns the result.
(Inherited from IVector)
As<U> Returns the object as a strongly typed vector of the specified type.
(Inherited from IVector)
AsCategorical Converts the vector to a categorical vector.
(Inherited from IVector)
GetCounts Returns a histogram of the number of observations in each group.
(Inherited from IGrouping)
GetIndexes Gets a sequence of indexes for the grouping.
(Inherited from IGrouping)
GetSlice Returns a new object that contains the values at the specified positions.
(Inherited from IVector)
GetValue Gets the value at the specified index.
(Inherited from IVector)
GetValues(IEnumerable<Int32>) Returns a new object that contains the values at the specified positions.
(Inherited from IVector)
GetValues(Int32[]) Returns a new object that contains the values at the specified positions.
(Inherited from IVector)
IsMissing Indicates whether the value at the specified index is missing.
(Inherited from IVector)
Protect Returns a shallow read-only copy of the vector.
(Inherited from IVector)
ReplaceMissingValues Replaces all missing values in a vector with the previous or next non-missing value.
(Inherited from IVector)
Sort Returns a permutation that can be used to sort the data in the vector in the specified order.
(Inherited from IVector)
WithCategories<T> Constructs a new categorical vector using the specified category index.

Extension Methods

Bin<T> Sorts values into bins and returns the result as a categorical vector.
(Defined by Vector)
Bin<T> Sorts values into bins and returns the result as a categorical vector.
