similar to: "tree-ID" in any segmentation package available?

Dear all, I am looking for a way to identify the row and column names of all elements within a matrix which fulfill some specified condition. Example: I have a correlation matrix of the following form: Y1 Y2 X1 0.4 0.3 X2 0.6 0.1 Suppose, I want to know which elements are smaller than 0.2, so the desired output should be something like: "X2 Y2" Thank you,

Hello, I've been using ctree and have developed a 55 node - 28 terminal solution. As can be imagined, the plot is difficult to travel down each of the major branches. I've read the help files for ctree I saw where terminal nodes can be color coded. plot(airct, type = "simple") > plot(airct, terminal_panel = node_boxplot(airct, col = "blue", + fill = hsv(2/3,

I have run the ctree function, and my dependent variable is broken into 3 categories: low cost, moderate cost and high cost. When i plot the results (eg. using plot(test.ct)), the plot shows, at the very bottom of each node, the probability of falling into each cost category. When i print the actual results (eg. using print(test.ct)), i get all of the backup

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

Dear R.Users, using ctree() (from "party" library) on a data.frame, I want to append a column with the references for the groups/segments detected. While these nodes are easy readable in output, I need a vector for my obs. Hints? Cheers -- Daniele Medri

Hello, I'm trying to use adabag to make bagging and boosting with bagging() and adabost.M1(), respectively, but in both cases it produces an abnormal termination of R. My code is: bagging(I.NOSOCO~EDAD+SEXO+ESTANCIA+ADMISI?N+T.CIRUG?+DURACI?N+CONTAMIN +PROFILAX+E.PREOPE+V.PERIFE+V.CENTRA+S.VESICA+S.NASOGA+DREN.ABI+DREN.CER

Hi all; Happy new year. I have got the following error rror in if (nrow(object$splits) > 0) { : argument is of length zero when I am running the following codes. train <- c(sample(1:27,18), sample(28:54, 18), sample(55:81, 8)) a2011.adaboost <- boosting(median_kod ~ ., data = b[train, ], boos=TRUE, mfinal = 10, control = rpart.control(minsplit = 0)) Regards, Greg [[alternative

Hello All, I am using library "party" and I have found a curious/strange behaviour when trying to save the output of a ctree in a file via jpeg/png command. If you use: ################ library(party) airq <- subset(airquality, !is.na(Ozone)) airct <- ctree(Ozone ~ ., data = airq) plot(airct, terminal_panel = node_boxplot, drop_terminal = FALSE) ############### you get a

Dear list, I want to perform a biplot, using customized titels for the x and y axis. Setting xlab="" and ylab="" resulted in an error, e.g.: > data(USArrests) > biplot(princomp(USArrests),xlab="",ylab="") Error in biplot.default(t(t(scores[, choices])/lam), t(t(x$loadings[, : length of dimnames[1] not equal to array extent > How do I

Hi! The postscript device in 0.90 does not produce symbols (pch=) as it should. E.g.: postscript(file="test.ps",width=8,height=6.4,horizontal=FALSE) plot(1:10,1:10,pch=1:5) legend(1,9,letters[1:5],pch=1:5) dev.off() The result looks quite different compared to the X-windows version. The symbol 1 (pch=1) is much to small, while the other symbols seem to big. Is it a bug? How can I

I have a Ubuntu server with an R installation that has 384 packages installed. We are trying to replicate the system on a Red Hat Enterprise server. I downloaded the list of packages from the Ubuntu machine and read it into an R session on the new machine. Then I ran install.packages(listofpackages). Now I have 352 packages on the new machine but several very common packages (like much of the

I am using debug on the .install_packages function...stepping through. Once the temporary folder is created and the tar file expanded I run file_test and get a FALSE back indicating that the configure file is not executable. [1] "/tmp/RtmpMM6iC1/R.INSTALLc5ca415e4310/stringi" Browse[2]> dir(new) [1] "DESCRIPTION" "INSTALL" "LICENSE"

Not much progress..... I step through debug and it gets to the do.install() function which immediately errors with the same "configuration not executable" error. So, made a tempfunc that was a copy of tools:::.install_packages and edited the file_test("-x","configure") line to return a TRUE now I get a Permission Denied error (even if I run as root) >

Dear R-List, I have a dataframe X containing factor f and numeric variable x1, x2, ... I want to create a new dataframe (or possibly a matrix) that gives statistics (e.g. sum) for the variables x1, x2, ... in each group defined by factor f. What is the simplest way to do this? I tried: attach(X) Z <- data.frame(f=levels(f),x1=as.vector(lapply(split(x1,f),sum))) and stumbled on: Error

I believe that is a locally defined function, which means you can set a breakpoint within it but only if R is compiled with source info, or you can manually call

I had the same thought in the shower this morning but I was disappointed to find that SElinux was disabled on the system. My next step will be to install a previous version of R on the system. My problem is that I am planning a shiny server installation and at least half of the apps on the current system depend on these libraries that will not install. -- W.

Following Duncan's instructions I find that the system and R find that configure IS executable but if trying to install via install.packages I get the same error. I also tried using R CMD INSTALL from the terminal and install.packages with a local file pointing to the very same tar.gz file that shows the executable bit set. All result in the same "configure is not executable" result.
