similar to: Bug in RODBC ?

Dear list, Working the example in Stats complements to V&R 3rd ed., I found this : > library(MASS) > library(mva) > data(farms) > plot(mca(farms,abbrev=TRUE),cex=rep(0.7,2)) # ... Works OK # Sheer curiosity ... > plot(mca(farms,abbrev=TRUE,nf=4),cex=rep(0.7,2)) Error in rep(p * X.svd$d[sec], c(n, n)) : invalid number of copies in "rep" A bit of exploration in the

I saw in the R-digest a thread about RODBC. 1) I think that this package is *extremely* valuable : it fulfills a need quite important in the case of iterative (e. g. periodic) analyses. No need to periodically return to your data and re-dumping them ... 2) The current version has a serious bug if your datasets has missing numeric values. M. Lapsley, the original author, is aware of it, but has

Dear all, I recently had to review the current litterature about some medical treatment with two possible variants (let's call them A and B). I collected all available prospective randomized trials about this treatment : I got four trials for the A variant and three for the B variant, all studies comparing one variant to a "suitably choosen" placebo. Two classes of variables are of

Dear List, I recently asked about any R implementations of Whitehead's methods for sequential clinical trials. Here's the summary of answers so far : 1) There is no R public implementation of those methods 2) There exists an interest for such a package, which does things quite different from Lan-deMets paradigm (shortly : Whitehead's methods allows for unplanned interim analyses

Dear List, I would like to know if there exist some R implementation of John Whitehead's procedures for the planning and analysis of group sequential clinical trials. His book is enlightenig but somewhat frustrating : it has a good basic exposition of his framework, but the technical details are sparse, and leave much work to do when one plans to reuimplement part of the procedures. For

This is an inquiry for all those who have been working on external data base applications. I sent an inquiry (below) to snews about this sort of thing a couple of years ago and eventually decided that I would wait to see what external database developments occurred and then revisit the problem. I hope that foundations are now better. Suppose for the sake of concreteness you have a large

Full_Name: David Whiting Version: 2.1.0 Under development (unstable) OS: linux Submission from: (NULL) (82.39.106.169) I have just upgraded from a previous version (2.0.0?) and found some of my code that used okay to run now gives an error. The function being called is sqlSave(). I am pretty sure (but not 100% certain) that the data frame I am trying to save has not changed. I am 100% sure that

Dear List, I have had problems inserting some (not all !) figures via odfWeave (using print(someLatticeFunction)...). The figure was correctly displayed in a R device window but the resulting ODF document displayed the correct space for the figure and an empty frame with a "broken image" icon and a "read error" mention. Exploration of the odf (.odt, in my case) file showed

A new release, called wine 0.9.3, is available on Debian/Ubuntu directory of the sf site. However, such a release has not beeen announced : winehq.org still advertises 0.9.2 as the last release. Is this a legitimate release with a late announcement, or an intrusion ? Scott ? Emmanuel Charpentier

Dear list, perusing the GMane archive shows that the issue with XML 3.4.x still bugs odfWeave users. I just checked that the newer XML 3.4.2 version still give the same problem. Using it to weave a bit of documentation written with LibreOffice 3.3.3 (current in Debian testing) leads me to a 192 Kb, 590 pages document, whereas reinstalling XML 3.2.0 gives me a 4 pages, 24Kb file (not

Dear list, I wish to define a set of functions *auxilliary* to another set of "main" ones, and I wonder if there is some "clever" way do do this using lexical scoping. Looking for that in the list's archives did not get me easily understood answers. Perusing MASS (1st, 2nd, 3rd and 4th editions!) and "Programming S" wasn't of much help either... R easily

Full_Name: Emmanuel Charpentier Version: 1.6.1 OS: Linux 2.4.20 / Debian Woody Submission from: (NULL) (80.15.78.96) rsprng depends on libraries available in the "genesis" package. However, even when Genesis is installed, the installation of the source package fails for not finding rsprng.h. It turns out that Debian installs it in a subdirectoru of /usr/include, and that the rsprng

Dear list, I have the following problem : I want to model a series of observations of a given hospital activity on various days under various conditions. among my "outcomes" (dependent variables) is the number of patients for which a certain procedure is done. The problem is that, when no relevant patient is hospitalized on said day, there is no observation (for which the "number

Dear list, Inspired by the original Knuth tools, and for paedaogical reasons, I wish to produce a document presenting some source code with interspersed comments in the source (see Knuth's books rendering TeX and metafont sources to see what I mean). I seemed to remember that a code chunk could be defined piecewise, like in Comments... <<Chunk1, eval=FALSE, echo=TRUE>>=

Dear list, "+" (and "-") being defined for difftime class, I expected mean() to return something sensible. This is only half-true : > mean(c(1:5, 5:1),na.rm=TRUE) [1] 3 > mean(as.difftime(c(1:5, 5:1),unit="mins"),na.rm=TRUE) Time difference of 3 mins Fine so far. However : > mean(c(1:5, NA,5:1),na.rm=TRUE) [1] 3 > mean(as.difftime(c(1:5,

Dear list, dear Max, I a currently working on a report. I'm writing it with OpenOffice.org and odfWeave. I'm working increentally : I write a bit, test (interactively) some ideas, cutting-and-pasting code to the Ooo report when satisfied with it. I the process, I tend to recompile the .odt source a *lot*. Suddenly, odfWeave started to give me an incomprehensible error even before

Dear sig-R-Debian I'd like to second Christophe Bonenfan's plea for an up-to-date Ubuntu 64 (and maybe an up-to-date Debian 64) repository(ies). There seems to be no "easy" way, at least for Debian 64, to stay up-to-date on a 64 bits Debian-derived system, "easy" meaning being able to keep a consistent system up-to-date with no local package creation and no

Dear List, I am (again) looking at meta-regression as a way to refine meta-analytic results. What I want to do is to assess the impact of some fixed factors on the results of a meta-analysis. Some of them may be crossed with the main factor of the meta-analysis (e. g. clinical presentation of a disease, defining subgroups in each of the studies under analysis), some of them may be a grouping

Dear list, This is a copy of a mail sent to Max Kuhn, original author and maintainer of the odfWeave package, which seems not to have received it. It reports a problem that seems to be very implementation specific (reproductible on three Debian testing amd64 machine, does *not* happen on two i686 Debian testing systems, does *not* happen on an Ubuntu 11.06 amd64 machine) and therefore not
