Dear Colleagues, does anybody know how to aggregate a data.frame using different functions for different columns?

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? Sincerely, ___________________ Markus Preisetanz Consultant Client Vela GmbH

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 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 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 R Specialists, when trying to cluster a data.frame with about 80.000 rows and 25 columns I get the above error message. I tried hclust (using dist), agnes (entering the data.frame directly) and pam (entering the data.frame directly). What I actually do not want to do is generate a random sample from the data. The machine I run R on is a Windows 2000 Server (Pentium 4) with 2 GB of

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 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 Sirs, I try to setup a quite complex routing scenario with iproute2, shorewall, bonding and hundrets of vlans as well as a lot of different virtual routing tables. In the past it was often possible to get great support directly by shorewall list but since the routing becomes more complex I do see a need to have a brief consulting by an experienced engineer. Shorewall list recommended me

Dear Nut-Devs, I have general question to the contribution and the handling of new code in the NUT-Project. We would like to implement our USV-Solution as a driver to NUT, but we are having the problem, that we need a powerful “C”-based gpio library for it. We discussed this topic internally, and we are having the opinion, that it does make sense, to write this library separate from a

Hi everyone, want to use R in our company but have to complete an intern questionnaire first. Can anyone help? Thanks in advance! Here the questions I’m not sure about: 1. Is R a Clientsoftware / Serversoftware / Systemsoftware? 2. Does R need a “chellenge-response” treatment for activation? 3. Is R proxy-able? 4. Is the personalised WINDOWS-NTLM-authorization at ISA-proxy

Hello List like described in the topic I have a problem with starting the libvirtd. I'm a complete newbie with libvirtd, today I heard the first time that such a daemon exists after I get the message that our webserver isn't running (a former colleague has installed this system). We have the following configuration: A Ubuntu based host on which our webserver runs within a qemu virtual

I don't know about the technicalities, but Peter Dalgaard said the offending code also causes R to come to a stop using SUSE + WINE. Is it possible to run that lot on top of valgrind? Of course, it will probably take all day ... If not, I have a clue which might help. The problem seems to lie in the "sub" routine. In the original report I used -- cut here -- gctorture() u <-
