The rtracklayer package implements support for a number of annotation and sequence formats. For example, you have a bed file with exon coordinates for human build GRC37 (hg19) and wish to update to GRCh38. Its main purpose is the visualization of genomic annotation tracks, whether generated through experimental data analysis performed in R or loaded from an external data source.
