I am looking for a function like my.blockwisesum(vector, n) that computes sums of disjoint subsequences of length n from vector and can work with vector lengths that are not a multiple of n. It should give me for instance my.blockwisesum(1:10, 3) == c(6, 15, 24, 10) Is there a builtin function that can do this? One could do it by coercing the vector into a matrix of width n, and then use

I personally belong to an (apparently fairly large) group of R users who may be enthusiastic, but are statistical laymen due to a lack of formal education in the area. The

Hello all, trying to prepare my first package for submission to CRAN I am stumbling over the "checking examples" step of R CMD check. I have some examples that produce more than one plot. I currently separate those plot calls by readline("Press <Return> for a plot including a density plot") or some such to have R wait before producing the next plot. This works OK

Hello everybody, I am just trying to put together my first own CRAN-able package. I have completed the programming and my code works OK. But now when I perform R CMD check agsemisc_1.0-2.tar.gz and R gets to the step * checking examples ... I receive the following error message: > print(bwplot(Species~Sepal.Length, data=iris, panel=panel.bwstrip)) Error in rep(T, length(x)) : T used

Full_Name: Lutz Prechelt Version: 2.2.1 OS: WinXP SP2 Submission from: (NULL) (130.133.8.114) This command plot(0, 0, xlim=c(3, 5), ylim=c(0, 10, 17)) should complain about 'ylim' (because it has three elements). However, it does in fact (in my german error message at least) complain about 'xlim' instead: Fehler in plot.window(xlim, ylim, log, asp, ...) : ung?ltiger

Looking back, 'par' would have been a likely candidate for looking. One reason I did NOT look there is that I need the functionality for print.trellis in

Dear Lattice bit-meddlers, while within a panel function for xyplot, how can I find out the values of (effectively) xlim and ylim -- no matter whether they have been set explicitly or chosen by Lattice itself? I have just tried for an hour to find out, with no success whatsoever. I looked in Grid for something that would return such data, but got lost. I looked at tracebacks of panel calls,

Hey.. Has anyone played around with Asterisk on the Itanium2, Opteron or Athlon64?? Can Asterisk (or Linux for that matter) actually make good use of a 64bit system?? Later..

Full_Name: Lutz Prechelt Version: 2.4.1 OS: Windows XP Submission from: (NULL) (160.45.111.67) I stack a number of data.frames using rbind. Each of these dataframes has a column 'authorname', which is a factor and a column author = unclass(authorname) as piecewise pseudonyms. When using rbind to stack these dataframes, R warns about invalid factor levels and inserts all NAs in the author

Samba Team, How do I create simulated load on a samba server? I wish to use feedback-directed program restructuring on AIX 5.2 to determine if performance can be improved by rearranging the executable generated by the IBM 6.0 compiler. Mostly I'm determining what the upper bound on smbd's is in a multiprogramming environment. I'm currently running about between 800 and 1000

Hello! Anybody know if there is a specific source of XEN to ia64 ? Could you pass me the link? I would like to install in a Itanium2. Thank you.

Hi, My company just bought a HP Itanium2 Server with Redhat Advance Server 2.1 preinstalled. I have set the Samba server on the server for the file sharing between Windows and Linux platform. The Samba server on this Linux is version 2.2.1a, it does not come with SWAT, therefore I need to add the user through command. After adding user to both Linux and Samba, I was unable to connect to the

Hi, R core developers, I work in the Swiss Institute of Bioinformatics. We have two clusters of Intel Itanium2 clusters for bioinformaticians to crank their data. One piece of software they use heavily is R and BioConductors. I ported the R codes and R packages to this platform already, and am working on optimizing their performance. I'm using Intel C/C++ compiler on this platform running

In your data frames, 'y' is a category and the following comment in the code makes clear this is deliberate. if( !is.null(levels(xj)) ) { all.levs[[j]] <- levels(xj) facCol[j] <- TRUE # turn categories into factors } else facCol[j] <- is.factor(xj) The behaviour is compatible with S apart from the comment in the R help

This is not a bug, nor is the subject line true: both do accept factors but what they do with factors is undocumented. From the help (not 'man') page Performs *set* union, intersection, (asymmetric!) difference, equality and membership on two vectors. ^^^^^^^ so it is not said to work on factors. I disagree that what intersect() for
