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

Dear R-users, I have some problems with the geweke.diag-Function of the coda-package. I try to obtain the Geweke-diagnostic by using the following, simple code: library(coda) input.geweke = as.mcmc(input.matrix) #input.matrix is a 25.000 x 35 matrix with the 25.000 saved draws of the 35 parameters of interest output = geweke.diag(input.geweke) However, I get the following

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

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

Dear R-Users! My aim is to produce boxplots without the outliers included in the plot. I started to write a function that looks something like: myboxplot <-function(x,fa) { bpdata <- boxplot(x~fa,plot=FALSE) bpnames <- names(bpdata) for (JJ in bpnames) { command <- paste("bpdata$",JJ,"$out <- numeric(0)",sep=""); eval(command) }

Hello! When I know the vector of the variance of the disturbances (i.e. the structure of heteroskedasticity), say Var(u_{i})=v_{i}, what is the weights I should use as argument to lm(): M <- lm(y~x,weigths=1/v) or M <- lm(y~x,weights=1/(v^0.5)) ??? In the help pages I did not find a clear answer to this question, so please could someone help me! Thanks, Wolfgang Koller

Hello list, I am writing a package which builds on a function ("foo") of another package. I only need that particular function. What is the state of the art to do this? Do I need a NAMESPACE file in my package? Currently I still don't have one. Or can I do this with the Imports field in my DESCRIPTION file? Reading chapter 1 of the "Writing R Extensions" manual I do

Dear R-developpers, currently the function window shows the following behaviour, if start or end is out of range: > x <- ts(1:14,start=c(1950,2),frequency=4) > y <- window(x,start=c(1950,1),end=c(1953,4)) Warning messages: 1: start value not changed in: window.default(x, ...) 2: end value not changed in: window.default(x, ...) Instead of this I would like it to fill with NAs the

Dear R-Users and Developpers, Currently R does not include functions to compute the skewness and kurtosis. I programmed it myself in the following way, but probably *real* programmers/statisticians can do that better: mykurtosis <- function(x) { m4 <- mean((x-mean(x))^4) kurt <- m4/(sd(x)^4)-3 kurt } myskewness <- function(x) { m3 <- mean((x-mean(x))^3) skew <-

So apparently (being a linux novice) I didn't realize it was insufficient to simply have the file marked as executable. It turns out the default TMP directory on my machine is mounted with a noexec flag so no files in that directory are allowed to be executed. The solution is to set an environment variable TMPDIR=some new directory I created (eg. /home/myusername/tmp) Then R uses that

I am sure I am providing insufficient information, please ask for more. I installed R 2.14.2 on my Ubuntu laptop with and AMD64 processor and also installed RStudio and everything worked fine. Now, I tried to build R 2.15.1 from source and installed it using defaults. RStudio now complained that R was not built as a shared library. Went back and uninstalled, and configured with -enable-R-shlib

I step through debug and it gets to the do.install() function which immediately errors with the same "configuration not executable" 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. Michael Conklin EVP Marketing &
