You can force an error by specifying all the default arguments. Using the version of zz with an all component it will encounter all= twice: > do.call(cbind, c(zz, all = TRUE, fill = NA, suffixes = list(NULL), drop = > FALSE)) Error in cbind(deparse.level, ...) : formal argument "all" matched by multiple actual arguments or more compactly: > do.call(cbind, c(zz, formals(zoo:::cbind.zoo)[-1])) Error in cbind(deparse.level, ...) : formal argument "all" matched by multiple actual arguments -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
