It is not clear to me that one can. If the singular value decomposition of A is the triple product P d Q', then the singular value decomposition of A'A=S is Q d^2 Q'. The information about the orthonormal matrix P is lost, is it not? ********************************************************** Cliff Lunneborg, Professor Emeritus, Statistics & Psychology, University of Washington,

As an alternative to the use of multiple shortcus to gain entry to different R environments on WIndows platforms I would like to suggest the use of two R functions written by my colleague John Miyamoto. I have taken the liberty of attaching their definitions to this message. Their efficient use is based on adopting the following regimen or something like it: (1) at startup attach an .Rdata

I am having difficulty coming to grips with Appendix B.2 of the otherwise very useful "An Introduction to R" and the related help file for Startup. I am running RGui 1.6.0 on a Windows 2000 machine from the default installation. How the concepts discussed in B.2 and the Startup help file relate to what I see on my machine is something of a mystery. I quote from the Startup file:

Hello R-help, I'm studying an example in the R book.? The data file is available from the link below.http://www.bio.ic.ac.uk/research/mjcraw/therbook/data/fertilizer.txt Could you explain Why the results from lme() and lmer() are different in the following case? In other examples, I can get the same results using the two functions, but not here...? Thank you.Miya library(lme4)library(nlme)#

Hi List, I am trying to look up an object using getAnywhere, where the object I am looking for is given by the _value_ of the variable I am looking for. Since getAnywhere calls substitue on its argument it is looking for an object with the name of the argument not its value. Is there a way to work around this, or do I have to make my own getAnywhere without the substitute? This is an example to

'getAnywhere' is not reporting methods when there are periods in the class name or the generic name (in R-devel). > getAnywhere( 'predict.loess') A single object matching 'predict.loess' was found It was found in the following places registered S3 method for predict from namespace modreg namespace:modreg with value <<...>> > getAnywhere(

Full_Name: Mark Bravington Version: 2.0.1 OS: Windows XP Submission from: (NULL) (140.79.22.104) 'getAnywhere' crashes when its argument starts with a period: > getAnywhere( '.onLoad') Error in exists(x, envir, mode, inherits) : invalid first argument One fix might be to replace the line if ( !is.null(f <- getS3method(gen, cl, TRUE))) { with if ( nchar( gen)

The function 'getAnywhere' crashes if given a non-existent name containing a period: > getAnywhere( 'nomethod.noclassforme') Error in get(x, envir, mode, inherits) : variable "nomethod" was not found However, 'getAnywhere' behaves gracefully if the non-existent name lacks a period: > getAnywhere( 'nomethod') no object named `nomethod' was

I ran into some very irritating behaviour I don't understand. Let me illustrate with the package gdata() and the function print.object_size() : > print(object.size(iris),units='Kb') 6.3 Kb > getAnywhere(print.object_size) A single object matching ?print.object_size? was found It was found in the following places registered S3 method for print from namespace utils

Here I think S3 dispatch is very natural. Try the following: page <- function(x, method = c("dput", "print"), ...) UseMethod("page") page.getAnywhere <- function(x, ..., idx=NULL) { name <- x$name; objects <- x$obj; if (length(objects) == 0) stop("no object named '", name, "' was found"); if (is.null(idx)) {

Shouldn't this work? > .a <- 5 > exists(".a") [1] TRUE > getAnywhere(".a") Error in exists(x, envir, mode, inherits) : invalid first argument getAnywhere doesn't seem to like the "." prefix.

Hi Using R 2.8.1. I have list object called "AuxData". Inside a browser(), get("AuxData") succeeds, while getAnywhere("AuxData") fails with the error "no object named ??AuxData?? was found". I'm curious to know if this could be a bug. If yes, I'll try to come up with a reproducible example. Thanks Ben

Dear all, I'm getting more and more frustrated with the whole S4 thing and I'm looking for a more advanced summary on how to deal with them. Often I get error messages that don't make sense at all, or the code is not doing what I think it would do. Far too often inspecting the code requires me to go to the source, which doesn't really help in easily finding the bit of code

Unfortunately, I don't see how it will allow me to search environments similarly/in the same order as exists/get(..., envir, inherits=TRUE) does it. getAnywhere() will search everything

Hello. I am trying to invert a matrix, and I am finding that I can get different answers depending on whether I set LAPACK true or false using "qr". I had understood that LAPACK is, in general more robust and faster than LINPACK, so I am confused as to why I am getting what seems to be invalid answers. The matrix is ostensibly the Hessian for a function I am optimizing. I want to get
