I added two data sets (.rda) to my package eha, but when I build the new
version I get:
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: ‘eha/data/swedeaths.rda’ ‘eha/data/swepop.rda’
In DESCRIPTION I have 'Depends: R (>= 3.0.0)'
After googling for a while (found nothing relevant in 'WRE'), I
understand that I have two options: (i) Change 'Depends' in DESCRIPTION
as suggested, and (ii) using save with 'version = 2' for the new files.
And, if I am recommended to choose (i), should I recreate the old data
files with 'version = 3'?
My guess is go for (i) and version = 3 for all data files, but I feel
that I need advise.
