Thanks for this advice! I guess that clusterExport() is also out of question in package code, then. > So use foo::bar instead of library(). I have found out that R Internals documents serialize() to use a very efficient representation for package environments (a pseudo-SEXPTYPE followed by the name). Does it mean that it is a good idea to pass unexported private worker functions to parLapply(cl, X, fun), since the package environment is not sent over network? -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
