seqNewVarData: Variable-length data

In zhengxwen/SeqArray: Data management of large-scale whole-genome sequence variant calls using GDS files

Variable-length data

Description

Gets a variable-length data object.

Usage

seqNewVarData(len, data)
seqListVarData(obj, useList=FALSE)

Arguments

len	a non-negative vector for variable lengths
data	a vector of data according to len
obj	a SeqVarDataList object or a compressed list (defined in IRanges)
useList	if TRUE, return a compressed List defined in IRanges (e.g., seqGetData)

Details

seqNewVarData() creates a SeqVarDataList object for variable- length data, and seqListVarData() converts the SeqVarDataList object to a list. seqGetData() returns a SeqVarDataList object for variable-length data; seqAddValue() can add a SeqVarDataList object to a GDS file.

Value

Return a SeqVarDataList object or a CompressedAtomicList object (e.g., IntegerList()).
