Hi R developers, On R-devel (2020-06-24 r78746) I am getting those two new exceptions during R check. I found a change which eventually may be related https://github.com/wch/r-source/commit/69de92b9fb1b7f2a7c8d1394b8d56050881a5465 I think this may be a regression. I grep'ed package manuals and R code for unique.default but don't see any. Usage section of the unique method looks fine as well. Errors look a little bit like internal errors.
* checking Rd \usage sections ... NOTE Error in unique.default(env_list) : LENGTH or similar applied to environment object Calls: <Anonymous> ... .get_S3_generics_as_seen_from_package -> unique -> unique.default Execution halted The \usage entries for S3 methods should use the \method markup and not their full name. * checking S3 generic/method consistency ... WARNING Error in unique.default(env_list) : LENGTH or similar applied to environment object Calls: <Anonymous> ... .get_S3_generics_as_seen_from_package -> unique -> unique.default I don't think if it is related but I build R-devel with extra args: --with-recommended-packages --enable-strict-barrier --disable-long-double I check with: --as-cran --no-manual To reproduce download current data.table from CRAN (1.12.8) and run R check Best regards, Jan Gorecki ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
