R-alpha: Minor plotting problems
1) There's a curious asymmetry between points and lines, in that you can do lines(...,type='p') but not points(...,type='l') (and more importantly, not points(..., type='b'), which probably *could* arise in real work) This isn't deliberate, is it? 2) Did I remember to report the adverse effect of having plot(x,y) coerce its argument to numeric? Several of my

R-alpha: R-W95
Seems to be working very nicely (and what a relief to see it actually working!), I've found only a few problems till now: a) Characters outside 0-0x7f seem to get encoded as CP850 or something, not Latin 1 (æøå keys on DK keyboard gives mu,degree,sigma). b) Infinite recursion crashed R. (I forget details, but it was something stupid like f<-function(x){if (x < 1) 1 else f(x)*(x-1)})

R-alpha: axes & plot boundary
I don't rcall seeing this one reported before: plot(...,axes=F) removes not only the axes, but also the plot boundary. The 'bty' parameter loses its effect completely. getting it back seems to require fiddling with par("usr") and rect() or lines() (Linux, Alpha-3) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200

R-alpha: User friendly functions
A loose idea for *post*-0.50 development I've been giving a some (but not all that many) thoughts to whether some of the conceptual difficulties facing newcomers could be avoided by having simplified functions for common operations. We already have parts of this, e.g. in Kurts ctest routines. Specifically, I was thinking about data frames: How about

R-alpha: x[NA]
Just curious. Current logic in both R and Splus has > (1:3)[c(T,F,NA)] [1] 1 NA Does anyone know *why*? It makes sense for integer indexing, but for logicals it seems to have some strange consequences - if you divide a dataframe according to some criterion, you get as many NA-filled records as there are missing values of the criterion added to *both* the group that satisfies the criterion

R-alpha: Rprofiles
The x11() window can be a nuisance to have popping up at startup (esp. on small screens) when you're not working with graphics. However, currently you can't get rid of it without modifying the systemwide Rprofile. Current logic is: Run $RHOME/library/Rprofile if ./.Rprofile exists run it else if $HOME/.Rprofile exists run that endif I think it should be Run $RHOME/library/Rsetup if

R 1.8.0 alpha
The countdown to R version 1.8.0 has begun. As a novelty, we now make preliminary source tarballs available somewhat earlier in the process. They will be found in http://cran.us.r-project.org/src/base with names of the form R-1.8.0alpha_2003-09-10.tar.gz The first one was created a moment ago; subsequent ones will be created by a cron job that runs at 05:00 local (Wisconsin) time.

Intro notes (1st pass, not for general circ.)
I've just gotten through translating my notes for the course in basic statistics for health researchers. I've placed a copy on ftp://blueberry.kubism.ku.dk/priv/R-intro.tgz This is essentially a translation of the Danish notes that I wrote during the Autumn of 1997 for use with Rsept, i.e. roughly R v.50. They lean heavily on the textbook, Altman: Practical Statistics for Medical

First R-2.0.0 alpha version
OK folks, We're warming up to the release of R-2.0.0 on Oct. 4 (aka 2004-10-04). There will be two weeks of alpha releases followed by two weeks of beta releases, starting today. The releases are made available via CRAN in http://cran.r-project.org/src/base-prerelease and the first one is there already. In case of urgency or CRAN failure, the releases will also be found at

R-alpha: GLM (from R-core)
As some of you may know, there has been formed a "core team" of developers, who can dig directly into the R source at Auckland and fix bugs etc., in order to speed up development. There is a mailing list for that group. This is necessary, because some of the bugs discussed are not publicly available (and hopefully will never be!), but one potential risk of the structure is that we forget

R-alpha: hist()
If you try hist(rnorm(100),lwd=2) with a recent snapshot, you get the exact opposite effect of what was earlier argued to be desirable in plots: you get fat axes and thin bar outlines. The cause is plain to see, at the end of 'hist': title(main = main, xlab = xlab, ylab = ylab, ...) if (axes) { axis(1, ...) axis(2, ...) }

R-alpha: na.woes
1) hist() does not take NA's. Incompatible with Splus, probably just a bug? 2) I do wish we could somehow get rid of the misfeatures of indexing with logical NA's: > table(juul$menarche,juul$tanner) I II III IV V No 221 43 32 14 2 Yes 1 1 5 26 202 > juul$menarche=="Yes"&juul$tanner=="I",] ...and you find yourself with a listing of 477
