Hi,

 I have a bed file which I converted to genomic ranges and ran coverage function to get the coverage of per base. How to visualize the per-base-coverage? Per-base-coverage visualization would be tough due to the huge size. Is there any function which plot coverage for each 10kB intervals?

Thanks!

You could use either Gviz or ggbio to do that. Gviz in particular has a comprehensive user's guide you could read.
