# Virtual

Namespace: Deedle.Virtual

Provides static methods for creating virtual series and virtual frames. Those provide necessary wrapping around IVirtualVectorSource values

### Static members

 Static member Description  Virtual.CreateFrame(...)  Signature: (indexSource:IVirtualVectorSource<'?661960> * keys:seq<'?661961> * sources:seq) -> Frame<'?661960,'?661961> Type parameters: '?661960, '?661961 Create a frame with ordinal index, containing the specified sources as columns. The index source should support lookup (which is used for series lookup, slicing etc.) The value source does not need to implement lookup - mainly ValueAt, merging and getting sub-source  Virtual.CreateOrdinalFrame(...)  Signature: (keys:seq<'?661958> * sources:seq) -> Frame Type parameters: '?661958 Create a frame with ordinal index, containing the specified sources as columns.  Virtual.CreateOrdinalSeries(source)  Signature: source:IVirtualVectorSource<'?661953> -> Series Type parameters: '?661953 Creates a virtual series with ordinal index. The parameter is IVirtualVectorSource that specifies how to access values in the series (and is also used to determine the size of the series index)  Virtual.CreateSeries(...)  Signature: (indexSource:IVirtualVectorSource<'?661955> * valueSource:IVirtualVectorSource<'?661956>) -> Series<'?661955,'?661956> Type parameters: '?661955, '?661956 Create a virtual series with an index and values specified by two IVirtualVectorSource values. The index source should support lookup (which is used for series lookup, slicing etc.) The value source does not need to implement lookup - mainly ValueAt, merging and getting sub-source
