I noticed that, unlike similar functions, 'by' does not use match.fun, e.g.
> by(iris, iris$Species, "summary") Error in FUN(X[[1]], ...) : couldn't find function "FUN" The 'by' code should have an initial line of: FUN <- match.fun(FUN) ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
