Annotate a series of genomic intervals using R as detailed as possible

Question

[octpus616]

HI,

I plan to annotate a series of genomic intervals using R. I am interested in their location on the genome and the corresponding features, such as whether they are in simple repeat regions, LTR regions, or coding regions (as detailed as possible). I know there are several annotation packages in R that can do this, but I am not sure which ones are most appropriate. Can you give me some advice?
