Hello, I would like to plot the results of a LDA analysis plotting the discriminant scores with the decission boundaries on it with rggobi. I have GGobi already installed on my computer. I have three classes, so the plot would be LD1xLD2 plus the decission boundaries. Here there is the code I use make the plot: library(MASS) data <- zgcppr273K.pca$x[,1:7] Tumor <-

The classifly package uses rggobi to visualise classification boundaries in high-dimensions. Given p-dimensional training data containing d groups (the design space), a classification algorithm (classifier) predicts which group new data belongs to. Generally the input to these algorithms is high dimensional, and the boundaries between groups will be high dimensional and perhaps curvilinear or

Hi Folks, I'm at the point where I'd normally install xgobi (which I've used and found very useful), but there is the alternative of ggobi (now at version 0.9). Would anyone with experience of both care to indicate the merits of either relative to the other? The other thing I can't make out too clearly from the ggobu website is quite what's involved in choosing between the

Hello, I am using R-2.4.1 with Rattle() i load Rdata (ttData) which has 2columns and 66 rows When i execute Explore under GGobi for visualization i am facing the problem, ---- libggobi-0.dll not found ---libggobi-0.dll was not found.... reinstalling the application may fix the problem i try install.packages("rggobi") its been installed from CRAN however when i use it from rattle()

Hello useR, Could you please tell me how to draw the decision boundaries in a scatterplot of the original data for a LDA or Rpart object. For example: > library(rpart) >fit.rpart <- rpart(as.factor(group.id)~., data=data.frame(Data) ) How can I draw the cutting lines on the orignial Data? Or is there any built in functions that can read the rpart object 'fit.rpart' to do

Hello All, I'm trying to install rattle from source on a AMD64 machine running etch. I have two packages installed from the etch backport (r-cran-rodbc and r-cran-rsprng) but all the rest installed from source. I'm trying to install rattle, but install.packages("rattle", dependencies=TRUE) Tries to install rggobi, which complains about the version of libggobi. Does

Hi, I've had no luck with the combination of R-2.0.1 and Rggobi/gobi (1.1-1 and 1.0-1 beta). I've tried a default configuration of ggobi, as well as one with all the plugins enabled. I'm using RedHat 9 Linux. The problem I'm experiencing is a segmentation fault when library.dynam is called from .First.lib ggobi appears to work OK from the command line. I had an earlier

On a ubuntu linux computer (Feisty, i386), I compile R and additional packages from source. The compiler is gcc 4.1.2. The problem is, I can run "sudo R" and successfully compile all packages (e.g., MASS, lattice) except rggobi. The error seems to be in display.c. My ggobi is in /usr/local/, which R can find. I don't think this is a dependence issue because install.packages(...,

Hi R users. I am experimenting with ubuntu 7.04 Feisty. I install the ggobi package with apt-get. I got almost all the packages, but when I try to obtain rggobi, I got this message: ------------------------------------------------------------------------------------------------- install.packages("rggobi") Aviso en install.packages("rggobi") : argument 'lib' is

Hi, I am trying to plot the following data so that it can be visually represented well. I tried the dotchart but I felt it was too spread out. Then I tried the barplot which is good enough for me. Is there a way to give the labels for the y-axis as in the dot chart? Also, I feel the grey level is confusing, so is there options for designs within the bars? I cannot use color as the journal wants

Hi my installation of ggobi (!) was successful, but when I try to install Rggobi as described on http://www.ggobi.org/INSTALL.html: as non-su: R_HOME=/usr/lib/R export R_HOME GGOBI_ROOT=/usr/local/src/ggobi export GGOBI_ROOT R_LIBS=/usr/lib/R/library export R_LIBS as: su ln -s $GGOBI_ROOT/lib/libggobi.so /usr/lib/. ln -s $GGOBI_ROOT/lib/libgtkext.so /usr/lib/.

Hello, I didn't give enough information when I sent an query before, so I'm trying again with a more detailed explanation: In this data set, each patient has a different number of measured variables (they represent tumors, so some people had 2 tumors, some had 5, etc). The problem I have is that often in later cycles for a patient, tumors that were originally measured are now missing (or

Hi, I'm newish to R and Ubuntu, and I've getting this error when I'm trying to install ggobi in R. Any suggestions?

hi - not sure if this is the right spot to ask for help on this, probably a basic question... I am trying to install ggobi on R running on Ubuntu Hardy - I am new to both Linux & R so the answer may be obvious & I'm just missing it. I have installed GGobi via synaptic, but trying to install rggobi I get the following error - there's some path problem but I don't fully

I am running 64-bit Ubuntu 8.04 and when I invoke rggobi the interactive graph displays but R crashes. See my sessionInfo() and a short example below. Ggobi and rggobi installed without complaints. Mark > sessionInfo() R version 2.7.0 Patched (2008-05-04 r45620) x86_64-unknown-linux-gnu locale:

I am currently using R 2.15.0 with R Tools 2.15 (in Windows XP). I downloaded the source for RGgobi and extracted it to a folder.   Then I tried compiling and installing with the following command and got an error message: ------------------------------------------------------------------------------------------------------------------ D:\Work\tmp>R CMD INSTALL --build

Hi, Has anyone out there written a function to take a data.frame as input and generate XML that conforms to the DTD for ggobi ("ggobi.dtd")? In other words, like a simple version of the writeSDML function in the StatDataML package, but using ggobi.dtd instead of StatDataML.dtd. It looks easy to write such a function to handle data.frames with only numeric data, but a bit of work with

Hi, The problem is most likely, you need to call a R CMD BATCH with your arguments and the R-script inside of a shell script that you submit to your qsub. Unfortunately we don't use qsub anymore so can't test it, but it should be as follows: R-script eg. test.R: > ##First read in the arguments listed at the command line > args=(commandArgs(TRUE)) > > ##args is now a list of

After installing rggobi, I get the following error when I try to load it: > local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg)) library(pkg, character.only=TRUE)}) Loading required package: RGtk2 Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

Dear all, please could you advise me on the following : I've written a R script that reads 3 arguments from the command line, i.e. : " args <- commandArgs(TRUE) TUMOR <- args[1] GERMLINE <- args[2] CHR <- args[3] ". when I submit the R script to a PBS HPC scheduler, I do the following (below), but ...
