Thanks to all who replied. array.test <- array(1:64,c(4,4,4)) array.test[1,1,1] 1 array.test[4,4,4] 64 Cool! -- Tony Long Ecology and Evolutionary Biology Steinhaus Hall University of California at Irvine...

All: Any ideas on how to do variance component estimation, or at least get Expected Mean Sqaures out of the modeling commands. Thanks. Tony Tony Long Ecology and Evolutionary Biology Steinhaus Hall University of California at Irvine Irvine, CA 92697...

Thanks for all the help. Brian Ripley clued me in first. I was running an older version of R (under Linux). When I spent the last few minutes upgrading to the current version life was good again. Thanks again!!! Tony...

All: Is the VEE option not implemented for programming reasons or does it not make statistical sense? It is described in the Celeux and Govaert reference. I am interested in holding orientation and shape constant but varying volume. Tony -- Tony...

Perhaps this is obvious...but is there anyway to create a matrix like object with has more than 2 dimensions. I want to estimate a bunch of var/cov matrices inside an index loop. It would be more computationally efficient...

I am running R version ??? under Redhat 5.2. It seems as though the --nsize object has no effct on the size of the allocated Ncells as determined using gc(). Yes, I have that much data.... That is if I...

All: I am getting an error code from the optimization function. The code is Error in optim(p,fun.LLike, lower=low, upper = up, method = "L-BFGS-B", : non-finite finite-difference value [0] If I add a trace=6...

All: Are there any functions out there for selecting all the points in a region of a plot. I envision something like the identify() function except one could circle a cloud of points (and perhaps a vector would be returned...

All: I apologize as I think I had this problem before, and misplaced my notes on the solution. I just tried to upgrade my version of R on a Redhat Linux computer. I downloaded and ran the rpm for R...

Sorry: I should have reproduced the "problem" with a simple example. I do this below. I think there is likely a switch I can change using par, but don't know what it is. The problem is the tick marks...

All: I am trying to use gam in a scatterplot smoothing problem. The data being smoothed have greater 1000 observation and have multiple "humps". I can smooth the data fine using a function something like: out <- ksmooth(x,y,"normal...

running R 1.4.1 on MAC and 1.2.2 on Linux When I use run binom.test with small N the results are a little perplexing to me >binom.test(9,20,p=0.5) gives the below...

All: I have a matrix, X, with a LARGE number of rows. Consider the following three rows of that matrix: 1 1 1 1 2 2 3 3 1 1 1 1 3 3 2 2 3 3 2 2...

All: I just upgraded my system to Redhat 7.0, and installed the RPM for R 1.2.2. I intall R 1.2.2 using the rpm -U xxxx command. When R is invoked from some directories it starts...

I am generating an array of similar plots using the par(mfrow=c(3,3)) method. Everything works fine except the plot only puts y-axis tick marks on cells in column one and x-axis tick marks on cells...

Simon: WOW! Truly remarkable! I was mostly just trying to document the problem in case it was a symptom of deeper problems, but this is incredible progress. Tony At 5:30 PM -0400 7/27/05, Simon Urbanek wrote: >On...

All: My version of R crashes upon start-up if there is a DVD in my laptop. The DVD does not have to be playing. This problem seems quite reproducible. My tiger upgrade was a clean install. Obviously I can...

All: I am attempting to allow multiple users on a linux system use some common functions. The problem I am having is that for some users their default library location is .lib.loc = "/usr/lib/R/library" whereas for other...

R is inefficient enough that if you need 12 processors you may consider writing your function in C. Alternatively you can identify the part of your R code where most your CPU cycles are being used and make that a...

Brian (and group): Whoops. I wrote the message meaning to look at the version number and fill it, but then somehow forgot. I am running version 0.63.2 (and with the compile-time settings below was not getting and...
