Source versions would only have been available with a nondisclosure agreement, and relatively few copies would have been distributed in source.

A colleague is receiving some data from another person. That person reads the data in SAS and it takes 30s and uses 64k RAM. That person then tries to read the data in R and it takes 10 minutes and uses a gigabyte of RAM. Person then goes on to say: It's not that I think SAS is such great software, it's not. But I really hate badly designed software. R is designed by

I don't think anyone denies that you *could* make an EXE to do all that. The discussion is on *how easy* it should be to create a single file that contains an initial "main" function plus a set of bundled code (potentially as a package) and which when run will install its package code (which is contained in itself, its not in a repo), install dependencies, and run the main()

If you index a vector with a vector that has NA in it, you get NA back: > x=101:107 > x[c(NA,4,NA)] [1] NA 104 NA > x[c(4,NA)] [1] 104 NA All well and good. ?"[" says, under NAs in indexing: When extracting, a numerical, logical or character ?NA? index picks an unknown element and so returns ?NA? in the corresponding element of a logical, integer,

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see...

A little while ago here we had a short discussion about Task Views - I think ignited by someone saying 'how many times do I have to say "have you read the Optimisation Task View?"?' and I poured some fuel on that fire by saying "Task Views" was a stupid name. Anyway, I did say that Task Views were rather brilliant, but were let down by their hidden position on the R

...bewilderment. I'm hypothesizing it's in the way the PACKAGES file is being constructed, but haven't tested that hypothesis yet - I'm sure the R-forge admins will fix this.

In response to an earlier discussion about finding the fastest/best/nearest CRAN site, I geocoded (using my geonames package) the locations of the CRAN sites returned by getCRANmirrors. I've mapped them here: http://www.maths.lancs.ac.uk/~rowlings/R/Cranography/ The geocoding may have got it wrong, so if CRAN site maintainers want to send me a real lat-long (in WGS 84 aka EPSG:4326) I'll

Would you care to share how your package installs its own dependencies? I assume this is done during the call to `main()`? (Last time I checked, R CMD INSTALL would not install a package's dependencies...)
