Hi,
You need to upgrade your version of R to at least 3.5.0, preferably newer,
which is presumably the version under which the data file was saved.
Note from news(), under 3.6.1, in the section regarding SIGNIFICANT
USER-VISIBLE CHANGES for 3.6.0:
Serialization format version 3 becomes the default for serialization and saving
of the workspace (save(), serialize(), saveRDS(), compiler::cmpfile()).
Serialized data in format 3 cannot be read by versions of R prior to version
3.5.0. Serialization format version 2 is still supported and can be selected by
version = 2 in the save/serialization functions. The default can be changed
back for the whole R session by setting environment variables
R_DEFAULT_SAVE_VERSION and R_DEFAULT_SERIALIZE_VERSION to 2. For maximal
back-compatibility, files ‘vignette.rds’ and ‘partial.rdb’ generated by R CMD
build are in serialization format version 2, and resave by default produces
files in serialization format version 2 (unless the original is already in
format version 3).
Regards,
Marc Schwartz
