similar to: help.start() on linux (fedora 8) when firefox alreading running - a way to open a new tab?

The code below create an nxn upper triangular matrix of one's. I'm stuck on finding a more efficient vectorized way - Thanks. --Dale n <- 9 data <- matrix(data=NA, nrow=n, ncol=n) data for (i in 1:n) { data[,i] <- c(rep(1,i), rep(0,n-i)) } data

I've tried without success to calculate interaction and main effects contrasts using R. I've found the functions C(), contrasts(), se.contrasts() and fit.contrasts() in package gmodels. Given the url for a small dataset and the two-way anova model below, I'd like to reproduce the results from appended SAS code. Thanks. --Dale. ## the dataset (from Montgomery) twoway <-

Hi, I''m trying to compile wxruby-1.9.2. This is my first time using rake. All I get is the following: (in /bld/lib/wxruby-1.9.2) rake aborted! can''t convert nil into String /bld/lib/wxruby-1.9.2/rakefile:48 (See full trace by running task with --trace) And with --trace: (in /bld/lib/wxruby-1.9.2) rake aborted! can''t convert nil into

Running the function below, tested using the cardiff dataset from splancs generates the following error. What changes do I need to make to get the function to work? Thanks. --Dale > gen.rpoints(events, poly, 99) > rpoints Error: object "rpoints" not found # test spatial data library(splancs) data(cardiff) attach(cardiff) str(cardiff) events <- as.points(x,y) ###

I've written the function below to simulate the mean 1st through nth nearest neighbor distances for a random spatial pattern using the functions nndist() and runifpoint() from spatsat. It works, but runs relatively slowly - would appreciate suggestions on how to speed up this function. Thanks. --Dale library(spatstat) sim.nth.mdist <- function(nth,nsim) { D <- matrix(ncol=nth,

It does appear the ess package on CRAN for Ubuntu 8.04 fails to install the file 'ess-sas-sh-command'. This prevents invoking SAS via 'M-x SAS'. http://cran.mirrors.hoobly.com/bin/linux/ubuntu/README.html --Dale On Fri, Jul 11, 2008 at 12:39 PM, Rodney Sparapani <rsparapa at mcw.edu> wrote: > Dale Steele wrote: >> >> I re-installed from Hardy packages on

Hi I''d like to put out a 1.9.3 release perhaps later this week/weekend. If you have a chance to test the build and samples esp with latest rubygems, please do. There are still some bugs on the list, and samples to do, but this should address all the build/install probs that have come up. And it would be good to get some testing and feedback on some of the new classes. A note on the

I'm trying to understand the behavior of seq_along in the following example: x <- 1:5; sum(x) y <- 6:10; sum(y) data <- c(x,y) S <- sum( data[seq_along(x)] ) S T <- sum( data[seq_along(y)] ) T Why is T != sum(y) ?

I have a data management problem which exceeds my meager R programming skills and would greatly appreciate suggestions on how to proceed? The data consists of a series of observation periods. Specific behaviors are recorded for each time period in the order each is observed. Their are 8 possible behaviors, coded as "i" "c" "s" "r" "v"

I'm doing a permutation test and need to efficiently generate all distinct subsets of size r from a set of size n. P 138 of MASS (4th ed) notes that "The code to generate this efficiently is in the scripts". I was unable to find this code on quick inspection of the \library\MASS\scripts file for Chapter 5 and 'subsets' is not a function in MASS. I did find this problem is

I would like to randomly shuffle a distance object, such as the one created by ade4{dist.binary} below. My first attempt, using sample(jc.dist) creates a shuffled vector, losing the lower triangular structure of the distance object. How can I Ishuffle the lower triangular part of a distance matrix without losing the structure? Thanks. --Dale x1 <- c(rep(0,4),1) x2 <- c(rep(0,2),rep(1,3))

I'm trying to write a small function (below) to compute Box & Cox transformations of x for arbitrary values of lambda. I'd like to specify a range of values for lamba (min,max,step) and am having trouble getting the for loop to work. Suggestions? Any pointers to resources for learning to write functions in R for neophyte programmers? Thanks. --Dale boxcox <-

I would like to be able to use two functions; qansari and pansari which are found in the function ansari.test. How can I evaluate these functions independently? Thanks. --Dale For example, when I load the function ... qansari <- function(p, m, n) { .C(R_qansari, as.integer(length(p)), q = as.double(p), as.integer(m), as.integer(n))$q } and

I'm applying a function (Cov.f) defined below to each element of a distance matrix. When I run the code below, I get a warning message (below) and elements of returned matrix [2,3] and [3,2] are not zero as I would expect. Clearly, there is an error... What am I doing wrong? Thanks. --Dale Warning message: In if (h <= phi) { : the condition has length > 1 and only the first element

Hello, When I attempt to use KDE 3.03 "konqueror" for help.start() I can't get the search engine to work but otherwise help.start() is OK. How should "konqueror" be setup for this? The response to the command is below: > help.start(browser= 'konqueror') Making links in per-session dir ... If konqueror is already running, it is *not* restarted, and you must

I'm stuck on how best to of find the distance between ordered integers (presented below as a birthday problem). Given the vector x, how do I most efficiently generate the vector x[i+1] - x[i]? Thanks. --Dale For example... set.seed(555) x <- sample(1:365, 10, replace=TRUE) x <- sort(x) x x[i+1]-x[i] --- --------------- 14 14 0 75 61 136 61 197 61 236 39 253 17 310 57 323

Is it possible to implement the Jonckheere-Terpstra test for ordered alternatives using the coin package: Conditional Inference Procedures in a Permutation Test Framework? I found jonckheere.test{clinfun}, but it uses a normal approximation when ties are present in the data. To make this concrete, I've include a small dataset.

Hi list I'm attempting to list windows shared printers in Unix. That's really all that I need and I can't install Samba on the machine I need to list the shared printers from. I started analyzing the smbclient code hoping to extract the necessary info but as you all know it's a daunting task. Certainly for a C novice. Which is why I want to ask if there is anyone out there who

Hello, I would like to upload windows printer driver to my Samba through the printer "Advanced tab" as described in that doc http://www.samba.org/samba/docs/man/Samba-Guide/happy.html#id2582657 but this tab is totally grayed. I can imagine it's a permission issue but I'm not sure at all. Any idea, Frederic
