Hi, I have just seen Stefan Steinhaus' web page : http://www.uni-franfurt.de/~stst/ncrunch.html I think it would be nice to include "R" as well. I have taken Forrest Young's email on stat-lisp list and changed the stuff for "R" :) Here it is: (someone please check this so we can also send it to Stefan Steinhaus.

Dear all, I am trying to get an estimate of the intercept for a linear model. In this case, I know the slope of the model, can anyone tell me how to constrain the formula in lm() so that it only estimates the intercept not the slope? Many thanks in advance, Sincerely, Liqing Zhang Dept. of Eco. Evol. Biol. Univ. of CA, Irvine email: lzhang at uci.edu >From VM Mon Apr 30 08:18:45 2001

Hello everybody, I am making a modified version of "Stephan Steinhaus' benchmark test for number crunching, v. 2, (see http://www.scinetificweb.com/ncrunch/ncrunch.pdf for the original version), comparing several functions of some math/stat software. R is not performing bad at all... except for the sorting of a 1,100,000 random vector (test #3) which is the worst of all (see cell F3 in

Dear List, I tested the example in the reposTools vignette: library(reposTools); Loading required package: tools genRepos("Test Repository", "http://biowww.dfci.harvard.edu/~jgentry/","newRepos"); Error in rep.int(colnames(x), nr) : unimplemented type 'NULL' in 'rep' Could someone help me out with this one? I'd appreciate all help.... I am

Hi, Can anyone help? I get the following error when trying to complie the h323 channel under the source installation directory asterisk/channels/h323 i have read the readme file and kept to the recomended versions; h.323 v1.12.2 and PWLIB v1.5.2 Thanks in advance [root@gw01 h323]# make g++ -g -c -fno-rtti -o ast_h323.o -march=i686 -DPBYTE_ORDER=PLITTLE_ENDIAN -DNDE BUG -DDO_CRASH

Hi, It turns out that two packages (1 Bioconductor, 1 CRAN) define an S4 class called "Annotated": library(S4Vectors) # see (*) at bottom for how to install library(RNeXML) 1st issue --------- getClass() issues the same warning twice: tmp <- getClass("Annotated") Found more than one class "Annotated" in cache; using the first, from namespace

Hi, I am having trouble installing the Open H.323 Channel driver in Asterisk. I have installed PWLib and OpenH323 V.1.11.7 This is the output l get before it bails out. asterisk:/usr/src/asterisk/channels/h323# make g++ -g -c -o ast_h323.o -march=i686 -DPBYTE_ORDER=PLITTLE_ENDIAN -DNDEBUG -DDO_CRASH -DDEBUG_THREADS -pipe -Wall -fPIC -Wmissing-prototypes -Wmissing-declarations -DP_LINUX

dear all, I try to update my Rversion fro 1.7.1 to 1.8.1 on linux. I have a problem when I try to install pacakges from Bioconductors with : source("http://www.bioconductor.org/getBioC.R") and getBioC(relLevel="release") somme errors append and when I make a library(affy) for example I obtain : > library(affy) Error in setIs("character",

Hi all, Just thought I'd post this (maybe) helpful tool I wrote. For people like me who are bad at keeping a clean environment, it's a time-saver. #simple command to get only one type of object in current environment lstype<-function(type='closure'){ inlist<-ls(.GlobalEnv) if (type=='function') type <-'closure'

Dear colleagues, there is a behaviour with S4 (virtual) classes that I find very hard to understand: Depending on the position of setAs(), the tree of inheritance changes. This is my baseline example that defines the classes "grandma", "mother", "daughter" and a virtual class "mr_x". For a new instance if "daughter", "mr_x" is betweeen

Hello, am I using 'setIs' in the correct way in the subsequent (artifical) example? Do I have to specify explicit 'setAs' for 'list' and 'vector' or should this work automatically, since "getClass("List1")" states an explicit coerce also for these classes. I'm working with R 2.0.0 Patched (2004-10-06) on windows 2000. Thanks for your

Dear all, I have been trying to create an R package. This has been successfull until I tried to define classes. Currently, my procedure is the following: Start R, load the function and class definition >tmp <- function (x) {x} >setClass("rpa", contains = "list", where=topenv(parent.frame())) Use package skeleton to create directory structure:

Hello, I recently tried Xen 3.0.3-testing on my 2x Opteron-244 SMP machine. Everything works well exept one detail, which is not unimportant to me: the powernow-k8 driver fails to switch frequencies. A closer look on the powernow-k8 source reveals, that some MSR write operations seem to be without any effect. A rdmsr() before and after the wrmsr() call reveals that no real change on the register

Hello, I am trying to install affy package in R as follow: >R CMD INSTALL -l lib ~/rstuffs/affy_1.4.32.tar.gz Then I get an error at the end: Warning message: There is no package called 'Biobase' in: library(package, character.only = TRUE, logical = TRUE, warn.conflicts = warn.conflicts, [1] "ProgressBarText" [1]

Hello: I modified benchmark used in http://www.informatik.uni-frankfurt.de/~stst/benchspl.txt now the attached code will work with R, except for last test for some reason (Sorry ran out of time to play with this). Immediate problem is that R does not show fraction of seconds. So, that kinda makes comparison some what hard. I also looked at memory and CPU usage on NT console. R seems to go

Doing it like this: genericForPrimitive <- function(f, where = topenv(parent.frame()), mustFind = TRUE) { ans = .BasicFunsList[[f]] ## this element may not exist (yet, during loading), dom't test null if(mustFind && identical(ans, FALSE)) stop(gettextf("methods may not be defined for primitive function %s in this version of R",

I have an S4 class with a slot of class "array", and in upgrading to 2.0.1 (from 1.9.1) I have encountered a change in behaviour. This causes me some difficulties if I want to allow 2-dimensional arrays in the slot. The following (in 2.0.1) illustrates the point: > setClass("foo",representation("array")) [1] "foo" > a <-

Hi all, The function call series genericForPrimitive -> .findBasicFuns -> .findAll happens 4400 times while the GenomicRanges package is loading. Each time .findAll follows a chain of environments to determine that the methods namespace is the only one that holds a variable called .BasicFunsList. This accounts for ~10% of package loading time. I'm sure there is some history to that

One more that might also be regenerated(?), but I noticed today that the live demo at http://llvm.org/demo/index.cgi now returns errors if you check the "Show LLVM C++ API code" box.
