[Rd] merge.data.frame bug report (PR#8676)
Merging data frames with no by variables does not append suffixes to column names to keep them unique. Also, shouldn't by=NULL be a legitimate way to get the "Cartesian product" of two data frames, instead of getting the error message "'by' must specify columns"? > df=data.frame(col=1:3) > merge(df,df,by=numeric(0)) col col 1 1 1 2 2 1 3 3 1 4 1 2 5 2 2 6 3 2 7 1 3 8 2 3 9 3 3 > > merge(df,df,by=NULL) Error in fix.by(by.x, x) : 'by' must specify column(s) > > sessionInfo() R version 2.2.1, 2005-12-20, powerpc-apple-darwin7.9.0 attached base packages: [1] "methods" "stats" "graphics" "grDevices" "utils" [6] "datasets" "base" > > version _ platform powerpc-apple-darwin7.9.0 arch powerpc os darwin7.9.0 system powerpc, darwin7.9.0 status major2 minor2.1 year 2005 month12 day 20 svn rev 36812 language R > Best, Todd Bailey __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Not actually documented to work? The documentation for merge says, "If the by.* vectors are of length 0, the result, r, is the “Cartesian product” of x and y". todd __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
[Rd] sub returns garbage (PR#8687)

[Rd] Compile R to WebAssembly / Emscripten?
Has anyone attempted to compile R (probably without any OS bindings) to WebAssembly / Emscripten? If so, how far did you get? (would be crazy awesome if you could get all the way to a ggplot bitmap output). If not, is this a waste of time or is there some daylight to doing this?

[Rd] \VignetteKeywords{}, for KEYWORDS or for free-tagging?
Hi R-devel, [Question]: * Is there a KEYWORDS file to lookup 'keywords' to supply the vignette command, '\VignetteKeywords{}'? -or, is the pkg writer free to tag the vignette using any keywords he/she chooses? i.e., free-tagging.

Re: [Rd] \VignetteKeywords{}, for KEYWORDS or for free-tagging?
Hi Kurt, Thank you for the info! However, I would also like to ask: * Since the user may use any words as 'keywords', what is the purpose of this command and what are the benefits of using it? * Where is the documentation for the '\Vignette*' commands? Because other than the '\VignetteIndexEntry' command, I could not find any mentioning of them in the R-exts manual, http://cran.r-project.org/doc/manuals/R-exts.html.

Re: [Rd] \VignetteKeywords{}, for KEYWORDS or for free-tagging?
Hi Kurt, Thank you very much for clarifying this. I hope that some documentation may be written about these commands and added to one of the manuals in the future. + Elliot On Wed, 5 Jan 2011, Kurt Hornik wrote: Elliot Todd Kleiman writes: Hi Kurt, Thank you for the info!

I don't think that the vignette metadata are currently used "a lot". They make it into the vignette index but users don't get to play with this. (There are long-standing plans to integrate vignettes into the help system [with help and help.search], though.)
