I got this wired behaviour of the attr() function using R-1.6.1 on both linux redhat 7.3 (i386) and Solaris 8 (Sparc): > tmp <- list(id=1) > > attr(tmp,"n.ch") <- 2 > attr(tmp,"n") <- 1 > tmp $id [1] 1 attr(,"n.ch") [1] 2 attr(,"n") [1] 1 > > attributes(tmp) $names [1] "id" $n.ch [1] 2 $n [1] 1 >

This might be because I didn't get it right, but; I thought R would release memory back to the system as (big) objects get removed? Here is my platform (with 1Gb of RAM): platform sparc-sun-solaris2.8 arch sparc os solaris2.8 system sparc, solaris2.8 status major 1 minor 3.1 year 2001 month 08 day 31 language R A little example: Start a new section of R, with

This is a little success story about the benefits of changing the defaults in config.site when I was building R-1.4.0 for Solaris (on a Sun Sparc that I'm currently using). For previous versions of R, I had just used the default config.site and not given it any thought. Since the Sun machine that I'm using is not getting any faster, I decided I would give config.site a look when building

I have been trying out R-1.6.0 tarballs (2002-9-10 and 2002-9-17) on: arch sparc os solaris2.8 system sparc, solaris2.8 status beta major 1 minor 6.0 year 2002 month 09 day 17 language R As you see form above, R-1.6.0 compiles fine and works. However, when I "make fullcheck" I get the following error: running code in 'tools-Ex.R' ... OK

I'm trying to find a good way of attaching a list within a function such that the attached variables (the list's members) precede the global environment (.GlobalEnv) in the search list. Here is a non-working example using attach(), which hopefully explains better what I'm trying to do: > foo <- function(x=0, input=list(a=10)) { + attach(input) + on.exit(detach(input)) +

Im trying to do regressions with constraints that the weights are all >=0 and sum(weights) = 1. I've read the archive and have set the problem up with solve.QP and just the non-negativity constraints along the lines of: y as the data vector X as the design matrix D <- t(X) %*% X d <- t(t(y) %*% X) A <- diag(ncol(X)) b <- rep(0,ncol(X)) fit <-

I have been playing around with sparse matrices in the Matrix package, in particularly with the Cholesky factorization of matrices of class dsCMatrix. And BTW, what a fantastic package. My problem is that I have to carry out repeated Cholesky factorization of a spares symmetric matrices, say Q_1, Q_2, ...,Q_n, where the Q's have the same non-zero pattern. I know in this case one does

Thank you Brian Ripley, Gardar Johannesson, and Marcel Wolbers for your prompt and friendly help! I will share any further learnings as I move through these suggestions. -Bob Abugov Brian Ripley wrote: I just use optim() on the sum of squares with non-negativity constraints.

Dear list, I have problems installing R-2.0.1 on SUSE Linux 9.2. I used the following commands in order install R in /usr/local ./configure --with x11 --with-readline make make install When starting R and trying to display a plot on the X-window system output is written to a postscript file.

Hello, I am doing mcmc=10000 simulations from a posterior distribution of the parameters of a mixture of K=6 normal densities. I have mcmc by K matrices simMeans, simVars and simWeights containing the simulation output: one row for each simulation, one column for each normal component of the mixture. One thing I would like to do is a plot of the posterior predictive density. In order to do that

Hi all, As far as I understood from the documentation of xgobi. The package is intended to plot data in 3D (and more). Why if I enter example(xgobi) nothing displays even though the example calls also the xgobi command (yes I did load the library)? Do I need to install anything else for xgobi to work? I use R 1.6.1. on Windows 2000 platform or R 1.5.1 with RedHat 7.3 (none works). Miha

I have been trying to get Xgobi to work with the function xgobi( ), but I keep on getting the message ""Xgobi requires a filename or some data from stdin" in the DOS-shell.

Hi, I am trying to use xgobi with R on a windows XP machine. I downloaded the package, which seems to have worked and started on the tutorial supplied.

Hi, Just started with exploring R. Nice ! (for many years using Splus). I tried to install and activate the package xgobi. - first download of xgobi.zip - then the R-command to install: install.packages('N:\\d024\\xgobi.zip',CRAN=NULL) - finally the command to attach the library: library(xgobi) Up to now, everything seemed to work. Also the help. No warnings that the

Hi, When I tried an example of the xgobi function, I got the following error. Could someone explain to me what is wrong ? Thanks a lot. xgobi(crabs,colors=c("SkyBlue","SlateBlue","Orange","Red")[rep(1:4,each=50)]) c:/PROGRA~1/R/R-23~1.1/library/xgobi/scripts/xgobi.bat -vtitle 'crabs' -std mmx

Dear colleagues, I just upgraded to 1.4.0 version from RH RPM on a RH72 linux i686 machine. Maybe I am the only one, but when I tried then to install 2 packages (namely pspline and xgobi), weird things happened. First on call of library(xgobi) or library(help=xgobi), all looks good, but on call of ?xgobi, or data(PaulKAI), or when trying to look at html help, the package seems empty. More
