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

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. When I try to run x11 with >x11() Error in X11(): X11 is not available. I do have a running

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 >

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

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 this 'odd' problem; I need to let R pause, for a given time, before starting next iteration in a loop. I'm using the following to do this task, but feel a little bit guilty because I'm using as much CPU time as I can get while pausing: while(keepGoing) { t.end <- proc.time()[3] + 5 ## the time this loop should end at [block of R commands] while(proc.time()[3]

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

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 <-

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.

R 1.6.0 has gone into final feature freeze as of today. As a new feature, we'll make interim beta versions available via ftp://cran.us.r-project.org/pub/R/src/base alias http://cran.us.r-project.org/src/base (filename R-1.6.0beta_*.tar.gz, where * is the creation date). If you want to help ensure that the final 1.6.0 works satisfactorily on *your* platform, it might be a good idea to

Dear all, I have a function "fn" with its own environment, i.e. env <- environment(fn) and env is not .GlobalEnv. And another function getValue <- function(x) environment(x)$mylist which returns the list object "mylist" which is in "env". If I want to modify "mylist", I could write 'getValue<-' <- function(x, value) {

If an attempt is made to attach to position 1, it appears to work (not even a warning) but in fact it doesn't work as many would expect. "search" thinks that it gets placed in position 2, but nothing is actually there (according to "ls"). This is guaranteed to be confusing (and annoying) to people who are used to attaching to position 1 in S-PLUS. I'm not clear on

Hi everyone, I'm an R newbie working with the poLCA module. I achieved my target without having to bother anyone, but It seems that I've got stuck at the last minute. My problem is simple. I need to write my results into a file. My results are in the shape of a list (unbalanced columns) I've considered several methods (sink(), write.file) etc. etc. Unfortunately, I'm not the best

Hi I just would like to know, When I have a dataframe, like this one called 'dummy' And I attach it. Then I run my code. I then update the dataframe by making changes and I still call it 'dummy'. I run my code again. Now dummy is at position 1 and position 2 of the search path and if I run the code again, with another version of 'dummy' it updates and eventually my search

Hello I tried to define replacement functions for the class "mylist". When I test them in an active R session, they work -- however, when I put them into a package, they don't. Why and how to fix? make_my_list <- function( x, y ) { return(structure(list(x, y, class="mylist"))) } mylist <- make_my_list(1:4, letters[3:7]) mylist mylist[['x']] <- 4:6

Hi I have a list : mylist <- list( a = NULL, b = 1, c = 2 ) > mylist[1] $a NULL > is.null(mylist[1]) [1] FALSE > is.null(mylist$a) [1] TRUE why? I need to use mylist[1]
