compute probabilities on a Bayesian Network
Deal R Users, I'm trying to find out how can I compute probabilities on a Bayesian Network using R. The Bayesian Network I modelled is shown at http://www.dsr.inpe.br/~mello/1727/BNgrapmodel.png and I'd like to know how can I proceed (commands on R) to answer questions like: (1) what is the probability of S=T given C=T, L=T, R=F, H=F and D=F; or (2) what is the probability of S=T

Time series of spatial data
Hi guys, I'm really new in R. Trying to analyze series of spatial datasets (365 satellite images) in order to find the best model that fit the data. Any suggestion which package that could help me? Thanks in advance. Cheers -- View this message in context: http://r.789695.n4.nabble.com/Time-series-of-spatial-data-tp3432979p3432979.html Sent from the R help mailing list archive at

force output dimension of table function
I have a small annoying problem. When I use the 'table' function on a simple vector it counts the number of occurences. So depending on the values of my input vector the function returns a class of type table with different lengths. Is there an easy way to tell the table function, the values to expect? That is ############# > set.seed(0) > s<-sample(0:5,5,rep=T) > s [1] 5 1

How can I include a new book on the "Books" link at R-project.org ?
I've just published a new book for R beginners in Portuguese: "Conhecendo o R: uma vis?o estat?stica" (something like "Knowing R: an statistical approach"). I'd like to include it on the list "Books" at R-project.org. How can I do it? More informations about the book at http://www.editoraufv.com.br/produtos/conhecendo-o-r -- Marcio Pupin Mello Survey

Cross-validation error with tune and with rpart
Hello list, I'm trying to generate classifiers for a certain task using several methods, one of them being decision trees. The doubts come when I want to estimate the cross-validation error of the generated tree: tree <- rpart(y~., data=data.frame(xsel, y), cp=0.00001) ptree <- prune(tree, cp=tree$cptable[which.min(tree$cptable[,"xerror"]),"CP"]) ptree$cptable

[LLVMdev] Building lld with Visual Studio 2012 RC
Hi! I'm trying to build lld Microsoft Visual Studio 2012 RC, but it seems the bzero function is not available. Could memset be used instead of bzero? Or maybe define a bzero for msvc using memset. For example: // in-memory matches on-disk, so copy first fields followed by path ::memcpy(to, (uint8_t*)&cmd, 12); ::memcpy(&to[12], _name.data(), _name.size());

[LLVMdev] Building lld with Visual Studio 2012 RC
OK thanks a lot Michael Spencer! After getting your latest commit now everything compiles on Visual Studio 2012 RC. I'm just playing around to learn. Maybe this is the funniest place to start assessing my possibilities of contributing to llvm in the free time: Writer* createWriterPECOFF(const WriterOptionsPECOFF &options) { assert(0 && "PE/COFF support not implemented

Possible problems with the git repository.
Howdy, I just did a git clone for the latest syslinux and when I entered the make command the build ended with an error. I also had to back level my git installation because "git clone url" doesn't seem to want to work any more yet it's what was on the web page.

repeating an analysis
Hi All, I have to say upfront that I am a complete neophyte when it comes to programming. Nevertheless I enjoy the challenge of using R because of its incredible statistical resources. My problem is this .........I am running a regression tree analysis using "rpart" and I need to run the calculation repeatedly (say n=50 times) to obtain a distribution of results from which I will pick

Dear R-devel, I am trying to alter rpart so that it makes additional calculations when growing the tree. In the "rpart.s" there is a call to the C routine: rp <- .C("s_to_rp2", as.integer(nobs), as.integer(nsplit), as.integer(nodes), as.integer(ncat),

Fine Tuning Country Map
Dear All, Please see the short script at the end of the email, which I assembled looking for bits and pieces on the web. It essentially does what I need: it plots several countries as a color-coded map. I just would like to fine-tune a bit the final image, in particular (1) Select my own colors for "painting" the countries (i.e. associate manually a color to every level) (2) Be

Winbind slow to authenticate
Finally got winbind to work, thanks for all the help. I wonder if it is normal for winbind to take approximately 20 seconds to authenticate a user? In smb.conf I have specified the names of all NT BDCs and PCD but it didn't change performance. And in pam.d/samba I have only auth and account required pam_winbind.so One more thing, does anybody have any hints on how to have Apache authenticate
