Dear all, I have a 100 iteration loop. Within each loop, there are some calls to rpart() like: ctl <- rpart.control(maxcompete=0, maxsurrogate=0, maxdepth=10) temp <- rpart(y~., x, w=wt, method="class", parms=list(split="gini"), control=ctl) res <- log(predict.rpart(temp, type="prob")) newres <- log(predict.rpart(temp, newdata=newx,

Hi R-helpers, I am using rpart package for decision tree using R.We are invoking R environment through JRI from our java application.Hence, the result of R command is returned in REXP and we use geterrMessage() to retrieve the error. When we execute the following command, cnr_model<-rpart(as.factor(Species)~Sepal Length+Sepal Width+Petal Length, method="class",

Hello, I think I've found a bug in the C function do_grep located in src/main/grep.c. It seems to affect both the latest revisions of R-2-13-branch and trunk when compiling R without optimizations and with it's own version of pcre located in src/extra, at least on ubuntu 10.04. According to the pcre_exec API (I presume the later versions), the ovecsize argument must be a multiple of 3 ,

Hi, I have installed openSUSE 10.2 (i586) and Wine 1.1.16. I am able to run the VB exe in SUSE and it connect to Sql server. In the VB application I have set Cntrl+F6 key to load another form. But any key combination with Cntrl key doesn't fire. Do I have to disable this Cntrl key combination in SUSE or Wine? Thanks

Something seems to have changed with the debugger option since I used it last, unless I've forgotten something really stupid (much more likely) . The debugger doesn't seem to recognise the names of C routines ***************** [jonm at localhost jonm]$ cat test.c #include "S.h" void test(int *x,int *y){ y[0]=x[0]+2; } [jonm at localhost jonm]$ R COMPILE test.c gcc

Dear R friends- I'm attempting to generate a regression tree with one gradient predictor and multiple responses, trying to test if change in size (turtle.data$Clength) acts as a single predictor of ten multiple diet taxa abundances (prey.data) Neither rpart or mvpart seem to allow me to do multiple responses. (Or if they can, I'm not using the functions properly.) > library(rpart)

Hi, I am using rpart decision trees to analyze customer churn. I am finding that the decision trees created are not effective because they are not able to recognize factors that influence churn. I have created an example situation below. What do I need to do to for rpart to build a tree with the variable experience? My guess is that this would happen if rpart used the loss matrix while creating

Hello! Ever since I used R on Windows (RGui) I am missing the ability to search the command history (Cntrl+R (reverse-search-history) in BASH, for example). Is there a particular reason for having this function disabled? Another feature would be word-wise delete (kill-word, backward-kill-word). Probably being able to use the Alt-key as Meta key for readline (instead of activating menu entries)

Dear R Team, A few monor typos in help pages that I noticed. Thank you very much. Rashid Nassar 1. help(gl) Examples: # First control, then treatment: gl(2,8, label=c("Ctnrl","Treat")) ^^^^ I assume "Cntrl" is meant. ========================================== 2. help(pmatch) Details: The behaviour

Hi, Using samba 1.9.17alpha5 on all servers, I'd like to configure one of my servers to be a failover domain controller in case my usual domain controller dies. Some verbage in BROWSE.TXT suggests that this is doable: { It is possible to configure two samba servers to attempt to become the domain master browser for a domain. The first server that comes up will be the domain master browser.

After a switch from Windows to Macintosh (running Mac OSX 10.6), I wanted to be able to run a dear old text editor, NoteTab Pro, which is only available in a Windows version. I did an installation using Wine, and after some initial issues in finding the supporting files to the editor (the path to them turned out to have 14(!) levels), everything was running smoothly. But pretty soon the MacBook

Hi, Been using rsync for many years but I'm stuck with this problem. I'ts a simplistic backup using rsync from a Windows 2k3 machine to a Linux box out on the 'net, using pre-shared ssh keys. In this case I'm saving, files belonging to various users, using the administrator account on the windows machine and the destination is a normal user account and its home file area.

Hello, I wrote a function in R which uses tcltk package .... essentially I wanted to give within that function, a widget with 2 radiobuttons to choose between plotting Precip and Temperature plots. After the user has chosen one of the radiobuttons there is another widget that asking him to identify outliers. However, I am having a lot of problems...what R does is evaluate the whole function

Hi there, I've a problem with rsync - see below. (by the way: I'm using rsync since 2 years now, good work!) my environment: - linux, 2.4, Dual-PIII-1.2GHz, 1 GB RAM. more of these machines. - rsync 2.5.5 - openssh 3.3 the machines are on a lan, so bandwith is not a problem. I sync large directories (about 6 GB growing) between the machines, no problem - memory consumtion of rsync is

Hello, I have a strange problem I have two applications called ADM and SGP When I start one or another it starts very fast, but the second hangs until I got to the terminal and I press crtl-c The message sent when i press ctrl-c is the following fixme:ntdll:RtlNtStatusToDosErrorNoTeb no mapping for c000013a After that it starts working

R community, I feel almost embarrassed to ask this question as it is strange behavior. When I think there's a bug around R or a package I ask "Self it's not a bug what dumb thing are you doing?" I'm running version 2.14.2 (2012-02-29) on a Windows 7 machine using the standard rgui Ever since I downloaded this latest version I have been having difficulty using the windows

Dear R-helpers, I am looking for a segmentation package that gives some "tree identifier" as output for every observation in the data set (my response variable is binary). I have skimmed through "rpart", "ada" and "adabag": The output "trees" gives you the formula, but I have to run several thousand segmentations on different data sets and it

I'm trying to understand how to set graphical parameters for trees created with the party package.  For example take the following code:   library(party)     data(airquality)     airq <- subset(airquality, !is.na(Ozone))     airct <- ctree(Ozone ~ ., data = airq,                    controls = ctree_control(maxsurrogate = 3))     plot(airct)   My problem is, I've got a ctree that has

Hello (I hope this is the correct group for this post - if not I am sure you will tell me where to go :-)) ) I use wine 0.9.23-12.1 in Suse 10.1 on my laptop to run Papyrus (a word processor originally written for the Atari platform and now available for Windows). I have been very pleased with recent versions of wine as it seems now to be working almost perfectly for Papyrus :-) However, I
