Dear Colleagues: I have 3 numeric variables (say x, y, z) in a data.frame and want to draw a 2D-scatterplot with the 3rd dimension as color, if possible without having to convert the whole thing to an appropiate matrix for image() manually. Can e.g. scatterplot3d do something like this? There's a function xyz.convert, but I couldn't find the way to use it properly. Sincerly,

Dear Colleagues, I've been looking for a function that can perform a tree analysis, similar to CHAID or QUEST. The key point is that in this case the variables are not binary but nominal (10 different values), so "tree" (from the tree package) won't work. Does anybody know help?

Dear Colleagues, does anybody know how to add dimnames to an image. Right now I'm using image(as.matrix(df3), col=brewer.pal(9,"Blues")) where df3 is a data.frame. dimnames(as.matrix(df3)) delivers [[1]] [1] "RFM_A1" "RFM_A2" "RFM_A4" "RFM_A5" "RFM_A7" "RFM_B3" "RFM_B6" "RFM_B7"

Dear Colleagues, I would like to only inspect rules that contain a certain label substring on the rhs. In this special case the item labels are built like this: <itemtype>_<itemvalue> e.g. "Artikelgruppe_E0815" what I want to do is only show rules where "Artikelgruppe" is contained in the rhs - has anybody an idea how this could work? Sincerely

Dear Collegues, when using sqlQuery from the package RODBC I always get a data frame with automatically generated rownames, even if: * the first column of the query is called rownames using "Select ... AS rownames, ... From ..." * and: the values from this column are unique * and: the values are inevitably forced to character data with e.g. " 'rn_' + CAST(xy AS

Dear Collegues, it seems like there is a problem with the image()-method in the package arules. Using an ordninary matrix works fine: image(matrix(rnorm(200), 10, 20), axes = FALSE, col=brewer.pal(9, "Blues") ) delivers an image with blue colors and no axes. Using an object of the class "associations" (arules package) does not work: image(items(ta.eclat), axes = FALSE,

Hi group, My case has N physicians with each seeing M patients. One physician could have seen a group of patients, or, a patient could have been seen by multiple number of physicians. In order words, there are overlaps. Now, I have the following NxM matrix Patient#1 Patient#2 Patient#3 ....... Patient#m Physician#1 1 0 1 ....... 0 Physician#2

Dear Collegues, does anybody know how I can place a legend at a sensible position in a star diagram automatically? The legend should tell the name of the variable (from colnames) for every color used.

Dear All I try to use your R package MCMCpack and I have encountered the following problem: The following code works fine: library(MCMCpack) line <- list(X = c(-2,-1,0,1,2), Y = c(1,3,3,3,5)) posterior1 <- MCMCregress(X~Y, data=line) summary(posterior1) But as long as I try the following lines library(MCMCpack) line <- list(X = c(-2,-1,0,1,2), Y = c(1,3,3,3,5))

Hello i have just tried to install the youtube Converter from DVDVideoSoft which should work fine with wine following the WineHQ.

Hiya, I'm currently running Wine 1.1.6 installed onto Ubuntu 8.04.1. Zu Online installed seamlessly, but when I run it from command line it fails quietly with no output.
