How can I define environments within a function so that they are visible to calls to a sub-function? I have defined an objective function, ProfileErr = function(params,...) which I would like to optimize using standard routines (optim, nlminb,....) but which contains auxiliary variables which need to be updated along with params. No optimization routine in R that I have found has facilities

Hello - I am having a problem with the function 'integrate'. I am running R on OSX (R 2.5.1). I am trying to suppress the error message when 'integrate' attempts to integrate across a parameter set giving a non-finite function value. I'm using it in a MCMC / simulated annealing algorithm, and it is entirely possible that some parameter sets will give non-

For a Monte Carlo study I need to extract from an lme model the estimated standard deviation of a random effect and store it in a vector. If I do a print() or summary() on the model, the number I need is displayed in the Console [it's the 0.1590195 in the output below] >print(fit) >Linear mixed-effects model fit by maximum likelihood > Data: datag2 > Log-likelihood:

While I recently received some very helpful files and email from Kevin Hendricks for compiling with ATLAS, thought I'd first have a stab at ACML. Having problems, which I suspect are trivial to solve: 1. machine is running RHEL 4, meaning, it uses gcc 3.4.5 out of the box, and g77. In my experience, over-riding RHEL's choice, and manually upgrading to gcc 4.x.x (and, as a consequence

Hi, We are having a problem with smbclient running tar back to a FreeBSD system for Amanda. smbclient seems to be choking on large files. Of the many singularly uninformative error messages, the primary error* is "invalid mid from server" Searching all FAQ's and news groups shows this has been a problem for several users since 8/2000 with no published response from anyone except a

I am moving from Samba 1.9.18 to Samba 2.2.2. I have figured out how to install printer drivers into the Samba server from a W2K workstation. But I can't figure out how Samba keeps track of which print queue uses which driver. Any help greatly appreciated. -Rick -- |Rick Cochran phone: 607-255-7618| |Cornell CIT - Systems & Operations - Net-Print

Normally, I do symbolics in Maple, or Mathematica, but I'm trying to write a simple script for students to handle some *very* simple calculations (for other purposes) with matrix or vector elements, where the elements are coded symbolically. What I've tried with *partial" success is use of the tilde (~) operator. So, for example, consider a simple vector: test=matrix(c(~

I have a query after finding an error running Rtools on a Windows machine. I am trying to build an update to the R fda library using Rtools27 under Windows XP Pro. This is the current fda library on RForge: http://r-forge.r-project.org/projects/fda Following R CMD build, R CMD check produces the following error in 00Install.out: installing R.css in F:/work/RForge/fda.Rcheck make: ***

Hi Andy, I know this topic has been discussed before on the R-help, but I was wondering if you could offer some advice specific to my application. I'm using the R random forest package to compare two classes of data, the number of cases in each class relatively low, 28 in class 1 and 9 in class 2. I'd really like to use R environment to analyze this data, however I'm finding it

Hi, All, I am getting some funny results trying to use R's built in distribution functions.

Hi all! My apologies for posting such a naive question. I've been trying to run multiple comparison contrasts on several GLM models. For doing so I've tried to use the mulcomp CRAN package. However, before I can make the package to work I have to load the mvtnorm package which I cannot find in CRAN (or anywhere else). Any inputs? Thanks a lot, /J Jose A. Andres. Post-doc Associate.

I'm seeking some advice on effectively using the new Matrix library in R1.9.0 for operations with large dense matrices. I'm working on integral operator models (implemented numerically via matrix operations) and except for the way entries are generated, the examples below really are representative of my problem sizes. My main concern is speed of large dense matrix multiplication. In R

Hi I have a question about the creation of variables within lists in R. I am running simulations and am interested in two parameters, ESM and ESMM (the similarity of these names is important for my question). I do simulations to generate ESMM, then plug these values into a second simulation function to get ESM: x <- list() for (i in 1:nsimulations) { x$ESMM[i] <- do_simulation1()

Samba 4.1.1 using BIND_DLZ (bind-9.9.1-0.1.P2) on CentOS 6.5 x86_64. I have two domain controllers, dc-1 and dc-2, which each have three network interfaces. Selinux is in permissive mode, and iptables is off. One interface on each dc is to be shut down. So, on dc-1, I do: # nsupdate -g update delete europa.icse.cornell.edu A 192.168.3.250 update delete europa.icse.cornell.edu A 192.168.3.251

I have three machines running libvirt under Scientific Linux (RHEL derivative) version 6. The virtual machine disk images are running SL 5 and 6, are all stored on NFS, and I can do live migrations with virsh migrate --live guestname qemu+ssh://vmhostname.math.cornell.edu/system Trouble is, within a day or two after the migration, the guest hangs up with repeated DriveReady errors and has to

Roland, Thank you very much for your attention to this. You should get a medal for all the help you give everyone on this list. On Sun, 10 May 2015, Rowland Penny wrote: > Why ? And why don't they show up when you ask for the zones with samba-tool ? I have that many subnets. As for why they don't show up: they are defined in BIND's configuration and not samba's; they never

Hi.... I am assembling an R package (under Windows XP, R v.2.3) and have a very basic question. Running R CMD build does not generate a pdf. R CMD check generates a .dvi, but I cannot figure out how to automatically create the pdf. I thought from reading the "writing r extensions' manual that R CMD build was supposed to generate the pdf. I am having no success using various

Hello. I am creating an R package that I'd like to submit to CRAN (OS Windows XP). How do I distinguish among 'public' functions, e.g., those that are intended to be called by users of the package and for which I am providing documentation & examples, and 'private' functions, which are used internally by the 'public' functions, but for which I do not wish to

I have several Qemu/kvm servers running VMs hosted on an NFS share, and am using virtlockd.
