stack1kg {ldblock} | R Documentation

## couple together a group of VCFs

### Description

couple together a group of VCFs

### Usage

    stack1kg(chrs = as.character(1:22), index = FALSE, useEBI = TRUE)

### Arguments

`chrs` | a vector of chromosome names for extraction from 1000 genomes VCF collection
`index` | logical telling whether VcfStack should attempt to create the local index; for 1000 genomes, the tbi are in the cloud and will be used by readVcf so FALSE is appropriate
`useEBI` | logical(1) defaults to TRUE ... use tabix-indexed vcf from EBI

### Value

VcfStack instance

### Note

The seqinfo component of returned stack will have NA for genome. Please set it manually; for useEBI=TRUE this would be GRCh38.

### Examples

    if (interactive()) {
      st1 = stack1kg()
      st1
      }
