Hi, The `quietly` argument of `require` is documented as follows:
quietly: a logical. If ‘TRUE’, no message confirming package attaching is printed, and most often, no errors/warnings are printed if package attaching fails. However: > require(foo, quietly=TRUE) Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, : there is no package called ‘foo’ Am I misreading the docs or is R misbehaving? > sessionInfo() R version 3.3.2 (2016-10-31) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under: macOS Sierra 10.12.1 locale: [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base Dan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
