In a package (say "clyde") that I am building I save a number of
datasets in clyde/data via something like:
When I build "clyde" I now get warnings like unto:
> WARNING: Added dependency on R >= 3.5.0 because serialized objects in
> serialize/load version 3 cannot be read in older versions of R.
> File(s) containing such objects: 'clyde/data/melvin.rda'
If I put the argument "version=2" into my save() call, the warnings go away.
What are the implications of this?
What are the consequences/what is the downside of setting version=2?
What are the consequences/what is the downside of adding the dependency
on R >= 3.5.0 into my DESCRIPTION file?
Who gets shafted by each of these two possibilities?
Which is recommended?
Grateful for any pearls of wisdom.
