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
???> y <- sort( c("a1","a2","a10","a12","a100")) > y[1] "a1" "a10" "a100" "a12" "a2"> mixedsort(y)[1] "a1" "a2" "a10" "a12" "a100" **Please read the docs!** They say that mixedsort() and mixedorder() both take a **single vector** as the argument to be sorted or ordered and, as the above indicates, they perform exactly as advertised. **Unlike order()**. So of course your do.call() construction fails. So presumably you have a data frame with multiple columns of mixed alpha and numerics? (A reproducible example would be most helpful here.) If this is the case, one **possibly dumb** approach (you have been warned!) would be to turn each column into an ordered factor and then call order() on the data frame of ordered factors via do.call() as above. i.e.> y1 <- ordered(y,lev = mixedsort(y)) > y1[1] a1 a10 a100 a12 a2 Levels: a1 < a2 < a10 < a12 < a100> order(y1)[1] 1 5 2 4 3 (this is just for 1 vector to show how the idea would work). Of course, if this is **not** what you want, you'll need to clarify, hopefully with a reprex. Or hope that someone else has better insight than I.

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)))

split any mixed columns into letter and number columns
and then order can be used on that:
DF <- data.frame(x = c("a10", "a2", "a1"))
o <- do.call("order", transform(DF, let = gsub("\\d",
"", x),
no
as.numeric(gsub("\\D", "", x)),
x = NULL))
DF[o,, drop = FALSE ]
