Hello all, We have a script that does a nightly backup of a windows server to a linux fileserver. The linux system uses smbclient to make a tarball of the share. I get this error when running smbclient: Domain=[OURSERVER] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager] tar: dumped 56781 files and directories Total bytes written: 9800680960 write_data: write failure. Error = Connection

Hi All, We have a mixed environment running with Windows and Linux with samba as the domain controller.  Smart card login is configured and working properly with pkinit and certs, etc (https://wiki.samba.org/index.php/Samba_AD_Smart_Card_Login) though I don't think this is related. A handful of Windows clients are regularly getting their accounts locked during what seems to be a

Goal: Suppose you have a vector that is a discrete variable with values ranging from 1 to 3, and length of 10. We'll use this as the example: y <- c(1,2,3,1,2,3,1,2,3,1) ...and suppose you want your new vector (y.new) to be equal in length to the possible discrete values (3) times the length (10), and formatted in such a way that if y[1] == 1, then y.new[1:3] == c(1,0,0), and if y[2] ==

Hi, I'm very new to R and absolutely love it. Does anyone know how to use something in R that functions like a BY command in SAS? For example, let's say you have a variable x, and you want to see the mean. Easy... > mean(x) But what if you want to see the mean of x conditional on another discrete variable? My best attempts so far are something like... > mean(x, y_cat=1)

Hi, I'm sure that a large fixed width file, such as 300 million rows and 1,000 columns, is too large for R to handle on a PC, but are there ways to deal with it? For example, is there a way to combine some sampling method with read.fwf so that you can read in a sample of 100,000 records, for example? Something like this may make analysis possible. Once analyzed, is there a way to, say, read

I want to apply a more complicated function than what I use in my example, but the idea is the same: Suppose you have a data frame named x and you want to a function applied to each variable, we'll just use the quantile function for this example. I'm trying all sorts of apply functions, but not having luck. My best guess would be: sapply(x, FUN=quantile) -- View this message in

Hi, I use R at home, and am interested in using it at my work company (which is in the Fortune 100). I began the request, and our legal team has given some gruff about the open source license. Not boring you with the details here, but I used some info on gnu.org as a rebuttal, and someone at the company replied that the generalities of GNU GPL may differ from R's specific GNU GPL license,

Hi, Is it possible in Sweave to put \Sexpr{} inside <<>>? This is a bad example, but here goes: <<results=hide>> Age <- 5 @ <<>> x <- \Sexpr{Age} @ I'm trying to get it to display x <- 5, rather than x <- Age. It's probably so obvious I'm going to feel sorry for having to ask, just the same, I'm stumped. Any ideas? Thanks. --

Does anyone know of a package that uses C code to calculate a multivariate normal density? My goal is to find a faster way to calculate MVN densities and avoid R loops or apply functions, such as when X and mu are N x K matrices, as opposed to vectors, and in this particular case, speed really matters. I would like to be able to use .C or .Call to pass X, mu, Sigma, and N to a C program and have

I'm trying to code more R-like and avoid loops. Here is an example I'm having a hard time getting away from loops with, and the real matrices are rather large, and the computation is too time-consuming. ### Dimensions N <- 2 M <- 3 P <- 4 ### Array and Matrices nu <- array(NA,dim=c(N,M,P)) Lambda <- matrix(1:12,P,M) F <- matrix(1:8,N,P) ### Loop to avoid for (i in 1:N)

Thanks to Brian Ripley, Douglas Bates, and Peter Dalgaard, who all pointed me towards the assembler (or compiler/assembler conflicts) as the likely culprit in my earlier "opcode" errors (most of original question below). After a lot of looking around, we found out that the particular alpha system we bought (from Microway) doesn't like the gnu compilers; it prefers Compaq's c

Can anyone show me how to refer to an object name that is passed to a function, from within the function? For example: MyModel <- 1 test <- function(x) { if(x == 1) {cat("x is a valid object.\n")} } test(x) What I would like this to do is pass MyModel to function test, and if it passes a test, be able to print "MyModel is a valid object." Thanks. -- View this

Hi, I am trying out a generalized least squares method of forecasting that corrects for autocorrelation. I downloaded daily stock data from Yahoo Finance, and am trying to predict Close (n=7903). I have learned to use date functions to extract indicator variables for Monday - Friday (and Friday is missing in the model to prevent it from becoming full rank). When I run the following code...

This should be very easy, but alas, I'm very new to R. My end goal is to calculate p-values from arima(). Let's say I just ran this: > MyModel <- arima(y[1:58], order=c(1,0,0), xreg=MyData[1:58,7:14], > method="ML") > MyModel And I see: arima(x = y[1:58], order = c(1, 0, 0), xreg = MyData[1:58, 7:14], method = "ML") Coefficients: ar1

Per the announcement from the MVAPICH team, I am pleased to let you know that the MPI-IO support for Lustre has been integrated into the new release of MVAPICH, version 1.0. > - Optimized and high-performance ADIO driver for Lustre > - This MPI-IO support is a contribution from Future Technologies > Group, Oak Ridge National Laboratory. >

Hi All, I have been reading about general purpose GPU (graphical processing units) computing for computational statistics. I know very little about this, but I read that GPUs currently cannot handle double-precision floating points and also that they are not necessarily IEEE compliant. However, I am not sure what the practical impact of this limitation is likely to be on computational

Greetings: I'm going to encourage some students to try Bayesian ideas for hierarchical models. I want to run the WinBUGS and R examples in Tony Lancaster's An Introduction to Modern Bayesian Econometrics. That features MS Windows and "bugs" from R2WinBUGS. Today, I want to ask how people are doing this in Linux? I have found a plethora of possibilities, some of which are not

I am trying to figure out if it is possible to run winBUGS from within R, using R2winBUGS, without having winBUGS spawn any windows (basically - 'true' batch - no GUI actions at all). The reason being I have a machine which I (and several others) ssh/telnet into, and would like to run winBUGS without having to mount a virtual desktop of any kind. I've looked through the r2winBUGS

Dear all, I want to run two winBugs process through R (by R2WinBUGS package). The first WinBUGS process can successfully perform under R. The error message appears while I put the code to run for the second WinBUGS. The error message: Error in file(file, ifelse(append, "a", "w")) : cannot open the connection In addition: Warning message: In file(file, ifelse(append,
