[R-pkg-devel] R CMD build --resave-data not working

[Sebastian Meyer]

This is a bug in R 4.0.0 - R 4.0.4 affecting packages using LazyData.

Two possible workarounds:

- Manually run tools::resaveRdaFiles() on your data directory before
building the package.

- Use a current development version of R (4.0.4-patched >= r80069 or
R-devel >= r79573)

Best regards,

	Sebastian Meyer
