I'm seeing some strange behavior while using the snow package for networked computers. I believe it's caused by name space resolution issues, and would appreciate any suggestions tracking it down. First, is there a way to find out what frame (as in frames in environments, not data frames) a name is being obtained from or put into? Second, how closely does the evaluation environment in

Hi, Newbie question about the pls package. Setup: Mac OS 10.3.9 R: Aqua GUI 1.01, v 2.0.1 I want to get R^2 and Q^2 (LOO and Leave-10-Out) values for each component for my model. I was running into a few problems so I played with the example a little and the results do not match up with the comments in the help pages. $ library(pls) $ data(NIR) $ testing.plsNOCV <- plsr(y ~ X, 6, data =

The function crossval (in library bootstrap) works well for the first degree polynomial model, but in the case of the second degree model I got an error message (see below). I would be very greatfull if somebody could give some advices for the following: > library(bootstrap) > > x<-c(22,23.4,24.9,28.5,29.8,31.6,34.2,36.4,37.7,39) >

Greetings, I have been exploring the use of the caret package to conduct some plsda modeling. Previously, I have come across methods that result in a R2 and Q2 for the model. Using the 'iris' data set, I wanted to see if I could accomplish this with the caret package. I use the following code: library(caret) data(iris) #needed to convert to numeric in order to do regression #I

Seems crossval from library(bootstrap) can only be used for leave-one-out and k-fold cross validation? Here is a dumb question, suppose n=80, how to do exactly leave-50-out cross validation? K-fold cross validation is not eligible for this case since n/ngroup is not an integer. Thanks!

Hi, I am trying to make a palaeoenvironmental transfer function using the R package rioja that predicts the water-table (measured as depth to the water table) of an area given the testate amoebae that are found there. I've carried out weighted averaging of the data and am trying to produce a graph that shows the observed water-table versues the model's predicted values. Following the

Dear R helpers I'm attempting to create a matrix of scatterplots with X-Y mean lines and regression lines added to each plot in the matrix. I have managed to create the first plot I would like using scatterplot but have run into an odd result when I use par() to set up the page to take multiple plot. Specifically, the mean and regression lines appear to plot in the second plot window, not

Hi, I was trying to do cross-validation using the crossval function (bootstrap package), with the following code: --------------------------------------------------------------------------------------------------------- theta.fit <- function(x,y){ model <- svm(x,y,kernel = "linear") } theta.predict <- function(fit,x){ prediction <- predict(fit,x)

Hi folks, I'm trying to estimate bias-corrected percentile (BCP) confidence intervals on a vector from a simple for loop used for resampling. I am attempting to follow steps in Manly, B. 1998.

Dear List, I have a problem building an R package using R 1.7.1 that I cannot resolve myself. R CMD check tells me that functions I documented properly in Rd-files are not documented and gives a TeX error at the end, altough the Rd files check is OK. I have three fucntions, one gets through without complaining, the other two don't. All the docu for the example data is also OK. I went through

Hi, I run into a problem with "R CMD Rd2dvi" command: it gives me "File `Rd.sty' not found" error (See the output message on the bottom). I get the same error when running "RCMD check". My system is: Windows 2000, R version 2.0.1, MiKTeX version 2.4. I do have a Rd.sty file in R_HOME/share/texm directory. I looked through newsgroups for any related discussions

Hi   I want to do leave-one-out cross-validation for multinomial logistic regression in R. I did multinomial logistic reg. by package nnet in R. How I do validation? by which function? response variable has 7 levels   please help me   Thanks alot Azam [[alternative HTML version deleted]]

Hi all, Has anyone tried to do k-fold cross validation for flexible discriminant analysis ( mda library), for example, using crossval() in bootstrap? The problem is that the function crossval() requires a separate matrix for predictors and another for responses, whereas the function fda(), using the formula argument only. Is there another way of doing k-fold cross validation for functions which

Hello, can anyone explain the following error I get when trying to use the CHECK command to check a new version of my pakcage under 1.4.0? ****** ./R CMD check ~/GLMMGibbs.0.5.1/GLMMGibbs * checking for working latex ...

Is there any way of getting just the LaTex output which R CMD Rd2dvi generates on the way to produces a .dvi file, which could then be incoorporated into another document?

Hi, This is a follow-up to the problem reported here: https://stat.ethz.ch/pipermail/r-devel/2010-September/058460.html After I updated R-2.12 to 2010-09-13 r52905 on the Bioc build system, some of the packages that have a Makefile in <pkg>/inst/doc still don't build on Windows. For example, 'R\bin\R.exe CMD build adSplit' gives: * checking for file

The NEWS for R 2.3.0 states that "R CMD check works for packages whose package name is different from the directory name in which it is located." However that hasn't been my experience. I ran R CMD check on package sources located in a directory with the same name as the package and it worked as expected. Then I renamed the directory and tried again. The first attempt got stuck

Hello, I am having an issue with R CMD check with the nightly build of RC 2.3.0 (listed in the subject.) The problem is this warning: * checking if this is a source package ... WARNING Subdirectory 'src' contains: README _Makefile These are unlikely file names for src files. In fact, they are not source files, but I do not see any reason why they cannot be there, or why I need to

I just installed R-1.7.0 on Darwin 6.6 (a.k.a. MacOS 10.2.6). 'make' and 'make check' run without any problems. 'make info' builds with no complaints, but 'make dvi' and 'make pdf' fail. I get refman.dvi and refman.pdf OK (with some warnings from pdftex that some names are referenced that do not exist), but R-FAQ.{dvi,pdf} fails as shown below. Attempts
