[R] Installed packages: Bioconductor vs CRAN?

Dear Bert,


The DESCRIPTION file contains additional useful information, e.g.:

1.) Package EBImage:
biocViews: Visualization
Packaged: 2021-05-19 23:53:29 UTC; biocbuild


2.) deSolve
Repository: CRAN


I have verified a few of the CRAN packages, and they seem to include the 
tag:

Repository: CRAN


The Bioconductor packages are different (see e.g. EBImage).

I am wondering if there is already a method to extract this info?


Sincerely,


Leonard
