#702

As stated in the issue, we were getting an "object of length > 1" warning but not seeing it, now it is an error. Also pkgdown was not building (in an issue that other packages had) where there was no print function defined for an object we were printing. @michaelquinn32

We need to do a release ASAP but I'm not sure why this wasn't caught by testing on the develop branch.

So overall the initial issue was that there was no print.one_skim_df. Then that then started the issue of reconcile_skimmers not working because of the warning now being an error.
Then it could not find the reassign_skim_attrs() and I tried many things but the one that worked was removing that tag.
Don't know why, or if that means we have no examples or tests that hit the other places with that tag.

@michaelquinn32 I think I replied to at least some of your comments can you take a look?

The main issue is that we were generating a warning and now it's an error. We just didn't realize there was a warning.

Sorry to keep pushing back, but I'm not sure this is still an issue that needs to be fixed. For example, here is the most recent r-devel check against our main branch. I don't see a warning. https://github.com/ropensci/skimr/actions/runs/3221419469/jobs/5269329413#step:6:36

I just put together a dev environment on a machine with R 4.2.1, and I didn't see any issues there either. Do you have an example where we have an issue with the current main or develop branch? If you can provide one, I can take another look.

Thanks! And I appreciate the patience with all of this.
