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?

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

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

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

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

I am trying to add confidence (error) bars to lattice barcharts (and dotplots, and xyplots). I found this helpful message from Deepayan Sarkar and based teh code below on it: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/50299.html However, I can't get it to work with groups, as illustrated. I am sure I am missing something elementary, but I am unsure what. Using R 2.1.1 on various

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());

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

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.

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),

Hi, I am reading the source code of rpart. I have problems understand the following code and would appreciate for any helps. In rpart.s, there is a line: rpfit &lt;- .C(C_s_to_rp, &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; n = as.integer(nobs), &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; nvarx

Hi everyone! In my new CentOS 4.0 (final ;-) I installed apache and activates SELinux, When I tried to enter a page of some user (localhost/~user) said to me that she did not have permissions to see it, and this was incorrect, because the permissions was 755 (/home/user/html). After awhile it was happened to me to deactivate selinux and I reinitiated the machine and I work! Somebody knows why

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

HI, Dear R community, I am writing the following function to create one data set(*tree.pred*) and one vector(*valid.out*) from loops. Later, I want to use the data set from this loop to plot curves. I have tried return, list, but I can not use the *tree.pred* data and *valid.out* vector. auc.tree<- function(msplit,mbucket) { * tree.pred<-data.frame()
