The rep function is very versatile, but that versatility comes at a cost: it takes a bit of effort to learn (and remember) its syntax. This is a problem, since rep is one of the first functions many beginners will come across. Of the three main uses of rep, two have simpler alternatives.
rep(x, times = ) has rep.int rep(x, length.out = ) has rep_len I think that a rep_each function would be a worthy addition for the third use case rep(x, each = ) (It might also be worth having rep_times as a synonym for rep.int.) While this could go in a package, since one of its main benefits is to help beginners, I feel it ought to go in base R. Before I submit this as a feature request, I thought I'd check here to see if there was any enthusiasm. Does rep_len sound useful to you? -- Regards, Richie Learning R <http://shop.oreilly.com/product/0636920028352.do> 4dpiecharts.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
