### Description

Set the visible region, by explicit chromLoc string, or by named features in any curently loaded annotation tracks

### Usage

    ## S4 method for signature 'igvR'
    showGenomicRegion(obj, region)

### Arguments

`obj` | An object of class igvR
`region` | A genomic location (rendered "chr5:9,234,343-9,236,000" or as a list: list(chrom="chr9", start=9234343, end=9236000)) or a labeled annotation in a searchable track, often a gene symbol, eg "MEF2C"

### Value

""

### Examples

    if(interactive()){
       igv <- igvR()
       setGenome(igv, "hg38")
       showGenomicRegion(igv, "MEF2C")
       x <- getGenomicRegion(igv)
          #--------------------
          # zoom out 2kb
          #--------------------
       showGenomicRegion(igv, with(x, sprintf("%s:%d-%d", chrom, start-1000, end+1000)))
