What are the differences between Blogdown vs. Quarto? I saw many posts (than I expected) who are switching from Blogdown to Quarto but based on example websites it looks like Blogdown is much smoother at loading all interactive posts/backgrounds compared to Quarto. I think this one difference can be a big advantage already for website builders. Then Why is Quarto so popular over Blogdown recently?

I'd do "cat" on the zfile to make sure it's an Rda. Also, if it's zipped (is that why you called it zfile?) then you may need to unzip first (rdas can be compressed when saving).

You should not use library() inside a package. You should use package::function() syntax. When you say "existing" R package, if that package is not yours, you should not do this unless you're planning on reaching out to that maintainer to incorporate (or potentially reject) these changes.

@@sreyarthamukherjee1642 You need to use devtools to build the package, see load_all and other devtools functions to build the package and check the package. You can't use library until you install that development version of the pacakage.
