Compatibility with ggplot2 4.0.0

[teunbrand]

Hi there,

We've been preparing a new major release for ggplot2 and found an issue during a reverse dependency check.
A reason for the major version change is a migration to an S7 backend for most classes in ggplot2.
This conflicts with some assumptions in ggedit, for example in the line below where theme elements are expected to be a list.

ggedit/R/themeFetchFull.R

Line 15 in deda87d

obj.class <- lapply(a[[obj.names[i]]], function(x) class(x)[1])

The problem popped up when executing one of the examples: compare(ggplot2::theme_bw(), ggplot2::theme_get()).
We sympathise that this is annoying, but would like to put the suggestion out there that it'd be good for us if ggedit put out a hotfix.

You can test your code with the development version of ggplot2 by installing it as follows:

# install.packages("pak")
pak::pak("tidyverse/ggplot2")

We aim to release the new ggplot2 version in about 2 weeks, and hope you can submit an update to CRAN around that time. Hopefully this will inform you in a timely manner.

Best wishes,
Teun

This is just a simple reminder.
