1- mixedorder does not work in a "do.call(mixedorder, mydataframe)" call like the order function does
This is tangential, but do.call(order, mydataframe) is not safe to use in a general purpose function either - you need to remove the names from the second argument: > d <- data.frame(method=c("New","New","Old","Old","Old"), result=5:1) > do.call(order, d) Error in match.arg(method) : 'arg' must be NULL or a character vector > do.call(order, unname(as.list(d)))  2 1 5 4 3 Bill Dunlap TIBCO Software wdunlap tibco.com On Sun, Mar 11, 2018 at 9:15 PM, Sebastien Bihorel < sebastien.biho...@cognigencorp.com> wrote: > Hi, > > Searching for functions that would order strings that mix characters and > numbers in a "natural" way (ie, "a1 a2 a10" instead of "a1 a10 a2"), I > found the mixedsort and mixedorder from the gtools package. > > Problems: > 1- mixedorder does not work in a "do.call(mixedorder, mydataframe)" call > like the order function does > 2- gtools has not been updated in 2.5 years > > Are you aware of an equivalent of this function in base R or a another > contributed package (with correction of problem #1)? > > Thanks > > ______________________________________________ > Remail@example.com mailing list -- To UNSUBSCRIBE and more, see > 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. > [[alternative HTML version deleted]] ______________________________________________ Rfirstname.lastname@example.org mailing list -- To UNSUBSCRIBE and more, see 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.
