Update tests

[teunbrand]

Hello there,

We have been preparing a new release of ggplot2 and during a reverse dependency check, it became apparent that the prospective ggplot2 3.5.0 would break santaR.

Several tests had expectations that the result of plot objects had length 9. This assumption no longer holds in the new version of ggplot2, so this PR updates these tests to test for the same length as ggplot() results.

To test the code changes with the release candidate, you can install it with the code below:

remotes::install_github("tidyverse/ggplot2", ref = remotes::github_pull("5592"))

The release of ggplot2 3.5.0 is scheduled for the 12th of February. The progress of the release can be tracked in tidyverse/ggplot2#5588. We hope that this PR might help santaR get out a fix if necessary.

Thank you @teunbrand for the reverse-dependency check and the PR addressing it, very much appreciated. We will update santaR accordingly.

Looking back at this, I apologise for the many spurious changes. Many of these are due to my editor stripping trailing whitespace when saving scripts and ought to be safely ignoreable.

This is just a kind reminder that the release of ggplot2 is scheduled soon.
