Filtered methylated sites annotation

Question

[dilrajkaur766]

Hi,

I have some filtered CpG sites with chromosome, gene, loc, start, and end positions. I want to annotate it with respect to the reference genome and visualise it. I tried 'annotateR' package but it didn't help.

Here is a sample of the file.
