Usage

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

Arguments

obj	An object of class igvR

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)))
