R Circlize Genomics

Question

[chimerajit]

Hi, I am trying to use R Circlize package for mapping genomic (SNP count data). I make ideogram with

circos.initializeWithIdeogram()

my data looks like this. ceach row have chr wise start-end and snp count(value)

chr start   end value

To plot this I did

circos.genomicTrackPlotRegion(data, ylim = c(0, 1),
    panel.fun = function(region, value, ...) {
        circos.genomicPoints(region, value, ...)
})

And this is working fine. I want to replace Points with barplot or histogram which is more useful for visualizing my data. How to do that?
