Dear R users: is there a package, similar to varclus in SAS or varclus in S, ported or written for R? Also, is there any other package in R that was designed for grouping the variables under different measures of distance (in cases where data is non-Gaussian, autocorrelated, and so on). Janusz. -- ** Janusz Kawczak ** ** UNC at Charlotte,

Hi all, Thanks for the wonderful forum with all the valuable help and comments here. I have been a splus user for the past 7 to 8 years and now crossing the mind of changing over to R. Have been doing a lot of reading and one of the main reasons is being an open source and the wonderful things that comes with that. My question is though, is it possible to export any of the function or librarys

I think people have been more than a little disingenuous in claiming that getting the Rmetrics package to go under Linux is transparent. If you have to dig into the

Concerning the Rmetrics packages, (1) There is a _much_ better thing to do than >simply ... to remove the stuff related to MS Win from zzz.R; > in partricular the lines after if( .... ) to clear your message. > As you can see, the info relates to the WinMenu under MS Win. as Janusz Kawczak suggests, and that is to *wrap* the troublesome code in if

This may be of interest to some of you. Janusz Kawczak.

Does anyone know whether R has its own modeling language for optimization problems (like SIMPLE in NuOPT for S-plus)? Paolo

I've compiled the 1.8.0 R on Solaris 2.9 and when trying to use plot command I get the Bus error and a core dump. Anybody experienced something like this? If yes, what should I patch? Janusz. [[alternative HTML version deleted]]

Heiner Schwarte has helped me with the AIX problem that I and Janusz Kawczak recently reported here. Heiner had found out earlier that there was a problem with the 'finite' c-library function [Heiner's test code see below] when gcc (and older versions of xlc) is used. He also found that instead, AIX defines a FINITE(.) macro itself in fp.h and that this would work in any case.

Hello, I've had a quick look on the list and can't find an answer to this niggle. Whilst debugging some code, I noticed that looping variables in R are not local to the loop as seams common in procedural languages. For example consider the following piece of code: for(i in 1:3){ cat(i,"") for(i in c("a","b","c")){ cat(i,"")

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails

Hi I have experienced problem with logon scripts on win2k clients with Samba 2.2.3a as PDC. It's just not run. WinNT 4.0 and Win9X clients don't show any problem. My samba.conf: [globals] server string = Serwer workgroup = HOME lock directory = /var/run/samba share modes = yes load printers = no client codepage = 852 character set = ISO8859-2 netbios name = GATE

I was playing around with a simple example using solve.qp ( function is in the quadprog package ) and the code is below. ( I'm not even sure there if there is a reasonable solution because I made the problem up ). But, when I try to use solve.QP to solve it, I get the error that D in the quadratic function is not positive definite. This is because Dmat is zero because I don't have a

When I try to build/install the quadprog package under R1.50 and NT4 it seems to have trouble finding blas routines. I'm currently using the generic blas routines, rather than ATLAS or some other tuned implementation: > Rcmd INSTALL d:/temp/quadrprog ... gcc --shared -s -o quadprog.dll quadprog.def quadprog.a quadprog_res.o -Lc:/a pps/rw1050/src/gnuwin32 -lg2c -lR

Hello, I have two vectors x1 and x2 both in increasing order. I want to select the x1[j]th entry which is the max min of the x2[i]th entry. I can do this using if and for statements but is there a quick way to do it without running a loop? Thank you in advance, Pantelis

I forgot to attach the problem data, 'quadprog.Rdata' file, in my prior email. I want to report a following error with quadprog. The solve.QP function finds a solution to the problem below that violates the last equality constraint. I tried to solve the same problem using ipop from kernlab package and get the solution in which all equality constraints are enforced. I also tried an old

Hi all, I read the setup at http://www.blackh0le.net/articles/vpn-dun-howto.html to setup my VPN. However, I'm having a problem which I think is proxy-ARP not working. I like to ask you to see if you know what's going on. When I ping 10.77.1.1 from windows XP machine the packets get to the 10.77.1.1 machine, but they don't have a return path to get back. When I do ping the windows

Dear R users, I am pleased to announce the release of three new R packages: optimbase, optimsimplex, and neldermead. - optimbase provides a set of commands to manage an abstract optimization method. The goal is to provide a building block for a large class of specialized optimization methods. This package manages: the number of variables, the minimum and maximum bounds, the number of non linear
