It only looks at the equivalent of typeof(), verifies the length() (which for data.frames is the number of columns) and then combines the objects along the axis that you're not interested in (building a list-matrix). I've been using the do.call(rbind, lapply(...)) idiom, relying on rbind.data.frame to check its arguments. It could probably be made more efficient, but it does the job. -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
