Parameters

keys IEnumerable<R>: A sequence of keys of the rows to return.

Return Value

DataFrame<R, C>
A new data frame containing only the rows whose index is in keys.

Exceptions

ArgumentNullException

keys is null.

GetRows(Subset)

Returns a new data frame that contains only the rows in the specified subset.

public DataFrame<R, C> GetRows(
	Subset subset
)

Visual Basic

Public Function GetRows ( 
	subset As Subset
) As DataFrame(Of R, C)

C++/CLI

public:
DataFrame<R, C>^ GetRows(
	Subset^ subset
)

member GetRows : 
        subset : Subset -> DataFrame<'R, 'C>

Parameters

subset Subset: A Subset that specifies the rows to return.

Return Value

DataFrame<R, C>
A new data frame containing only the rows in subset.

Exceptions

ArgumentNullException	subset is null.
DimensionMismatchException	The original length of subset does not equal the number of rows in the data frame.

GetRows(Vector<Boolean>)

Returns a new data frame that contains only the rows specified by a boolean mask.

public DataFrame<R, C> GetRows(
	Vector<bool> mask
)

Visual Basic

Public Function GetRows ( 
	mask As Vector(Of Boolean)
) As DataFrame(Of R, C)

C++/CLI

DataFrame<R, C>^ GetRows(
	Vector<bool>^ mask
)

member GetRows : 
        mask : Vector<bool> -> DataFrame<'R, 'C>

Parameters

mask Vector<Boolean>: A boolean vector whose elements indicate whether the corresponding row should be included in the new data frame.

Return Value

DataFrame<R, C>
A new data frame containing only the rows whose corresponding value in mask is true.

GetRows(R, R)

Returns a new data frame that contains only the rows specified by a range.

public DataFrame<R, C> GetRows(
	R firstKey,
	R lastKey
)

Visual Basic

Public Function GetRows ( 
	firstKey As R,

        lastKey : 'R -> DataFrame<'R, 'C>

Parameters

firstKey R: The key of the first row to be included in the result.
lastKey R: The key of the last row to be included in the result.

Return Value

DataFrame<R, C>
A new data frame containing only the rows with a key between firstKey and lastKey.
