[R-pkg-devel] How to fix "Number of redirects hit maximum amount"?

[Spencer Graves]

Hi, Uwe and Ben:


Thanks for the replies. That URL worked just now in Firefox, Safari and 
Chrome on my Mac and in the browser on my iPhone in Kansas City, 
Missouri, USA.


It's in the documentation for "The California Test Score Data Set" 
(Ecdat::Caschool), which was created years ago by Yves Croissant, a 
professor at the University of Lyon, France, and author of (2024) 
Microeconometrics with R (https://ycroissant.github.io/micsr_book/) and 
several other publications that use R.


The fact that it didn't work for Uwe worries me.[1]


I hesitate to degrade the work of Yves Croissant. I plan to document 
this in "cran-comments.md" and proceed with the other checks outlined in 
Wickham and Bryan, "R Packages". The current version on GitHub has green 
check marks on 5 platforms. As I mentioned, "R CMD check --as-cran" 
locally flagged several URLs that I have checked multiple times and 
found them good -- but did NOT flag "cde.ca.gov".


Reasonable?
Thanks again.
Spencer Graves
