Hi, I tried to inverse a matrix but it doesn`t work. I hope somebody can help me. This is what I did. > kurse <- read.table("kurse.txt", header=T, dec=",") > x <- cbind(1,kurse[,-c(1)]) > y <- kurse$index > t(x) %*% x Error in t(x) %*% x : requires numeric matrix/vector arguments > x <- as.matrix(x) > xtxi <- solve(t(x) %*% x) Error in

Hi, in approximately one months time mentoring institutions can propose projects for the Google Summer of Code 2009, see http://code.google.com/soc/ Last year the R Foundation succesfully participated with 4 projects, see http://www.r-project.org/SoC08/ for details. We want to participate again this year. Our project proposals will be managed by Manuel Eugster (email address in CC). Manuel

Hi there, I'm not able to get winbind to work, although searched google and studied and tried nearly every howto and forum entry on the net the last week.... it simply doesn't work and I don't understand why.... My Samba3-Domain SUPZ (samba & ldap Linux PDC, Windows Clients) works perfektly with all ldap users, groups (linux and from windows) and computer accounts (Win2000 WS).

Dear useRs and developeRs, I hope all attending useR! in Dortmund last week had as much a good time as I had and a safe trip home. This email is to announce our plans for forthcoming conferences. In 2009 there will be a useR! in Rennes, France (July 8-10), directly followed by a DSC in Copenhagen, Denmark (July 13-14). We would like to have a useR! 2010 in North America, and 2011 in Europe.

Not sure who to send this to... On the books page http://www.r-project.org/doc/bib/R-books.html the entries from [54] down have three forward slashes in the hyperlinks to publisher info and so they don't work Robin [[alternative HTML version deleted]]

Hi - Writing to see if someone can suggest whether a problem warrants a bug report. It concerns the use of stepFlexclust in the flexclust package. The problem concerns the size of clusters returned. Versions: R-2.7.0 on Windows XP; RODBC_1.2-3 code snippet: r8 <- stepFlexclust(df,8,nrep=100,FUN=kcca, family=kccaFamily("kmedians")) summary(r8) ## returns cluster sizes of 51, 115,

Dear all, I have just found a 'good' tutorial R for datamining. I think it should be on the contributed docs. http://cran.r-project.org/other-docs.html Here is the link http://www.liaad.up.pt/~ltorgo/DataMiningWithR/ What do you think?

Hi the devel list, I am using K means with a non standard distance. As far as I see, the function kmeans is able to deal with 4 differents algorithm, but not with a user define distance. In addition, kmeans is not able to deal with missing value whereas there is several solution that k-means can use to deal with them ; one is using a distance that takes the missing value in account, like a

Dear List, I'd like to set up a package repository so I can use install.packages() on it for home-grown packages. I set up an AMPP infrastructure on a windows box already, but I'm pretty lost with respect to what to do next as I didn't do any web-programming/admin yet. Could anyone recommend some r-specific tutorials or has a couple of suggestions for me? I've had a look at the

Dear R experts, we are preparing an R-package to compute the Oja Median which contains some C++ code in which random numbers are needed. To generate the random numbers we use the following Mersenne-Twister implementation: // MersenneTwister.h // Mersenne Twister random number generator -- a C++ class MTRand // Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus // Richard J.

The first patch is just some simple refactoring. See the second patch for a description of the new virt-sparsify --tmp option. I tested this using a loopback device as my temporary block device, and it seems to work fine for me. Federico .. this needs a BZ :-) Rich.
