this is what I did.

Could you please help me how to make it work.

Thanks for all the amazing resources provided

  There is a binary version available but the source version is later:
            binary source needs_compilation
rtracklayer 1.43.3 1.44.0              TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) Y
