Daniel, can you check if it's sensible to have 2 URLs (do other packages do this, how does this look on CRAN) or should we switch to io only?

[D-Maar]

It is intended to be able to have more than one URL.
Examples:
https://cran.r-project.org/web/packages/ggplot2/index.html
https://cran.r-project.org/web/packages/rhub/index.html
Some further information:

Short summary: The URL field is used for one or more URLs, which give additional usefull information to this package.

I would approve the change of having both URLs.

OK, then why not! I will merge. Thanks!
