Hi everyone, I'm taking a course in statistics as part of my doctoral program in education at the U. of Minnesota, USA. I found R via Rpy, a python module that makes it possible to use R from python scripts. The instructor refers to SPSS a lot and that seems to be the standard stats tool around here. But being more of a Unix guy and not intimidated by programming, I'd like to see if I

Thanks to Brian Ripley for the time and effort put into developing the factanal package for R. I have found it very useful. However, in trying to replicate some results from previous research, I have run into the need for a couple of extensions and was wondering if they might find their way into future implementations. 1. Though maximum likelihood estimates might be more rigorous and

How hard would it be to have rsync do the file recursion scan on both the source tree and the destination tree at the same time in parallel? Would that require a protocol change, or could just a program change be enough? I have some very large directories I'd like to syncronize. Total time to scan through these millions of files is a substantial portion of an hour or even exceeds it. It

This message describes (imho) a behaviour bug in rsync. I'm going to submit a patch, but before I dive into the code I want to know what the actual desired behaviour should be. In other words, please comment. I have some directories I want to keep synchronised between two machines (call them "master" and "backup"). Every now and then someone deletes a file on

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hy folks, everybody knows, that rsync eats up a lot of memory, when rsyncing a lot of files. To avoid this i run rsync on different parts of the directory-tree (e.g. first ~muchofileuser/muchofilesdir1 then ~muchofileuser/muchofilesdir2 and so on) and it works fine for me. So i tried to do this in a automatical way (e.g perl/shell/whatever

I am having a problem with two models that each have a HABTM relationship to the other. For example: CREATE TABLE people (id INT, name TEXT); CREATE TABLE teams (id INT, name TEXT); CREATE TABLE people_teams (person_id INT, team_id INT); The person model has: has_and_belongs_to_many :teams And the team model has: has_and_belongs_to_many :people The trouble comes when trying to destroy

Hi all, [Please CC me in replies, I am not subscribed to this list.] First of all, thanks for puppet! It is a very nice tool and I''m in the (slow) process of using it to manage my new Xen-based virtual server farm with it. Most of the "simple" tasks worked well so far, and I may be able to add a few recipies to the Wiki when I find time to do so. However, is there any way

I have a file in fwf. It is rather large, about 40,000 rows and 40 variables (columns). I only need about 10 variables form the data set for the analysis at hand. Unfortunately, these 10 variables are not contiguous in the file, for example, the first is position 1-8, the next position 25-27, then 40. Is there a way to read the selected varaibles that I need without reading in the entire data

Hi there, I have written a function to calculate factorials as follows: fact <- function(x) { recurse <- x > 1 x[!recurse] <- 1 if( any(recurse) ) { y <- x[recurse] x[recurse] <- y * fact( y - 1 ) } x } I want to be able to do the famous birthday problem, which will involve the computation of 365!, however it shall get cancelled

Hello R-Helpers, plot(x, y, type="b", pch="1") plots x vs. y with both a line and the symbol "1" but how do I change the "spacing" of the symbol being plotted. In other words, I don't want to plot the "1" at every data point, but only at every kth point (things get too cluttered when there are many data points). Thanks in advance! --

Hi, I wanted to compute the value of the function ifn at certain values of n. But I am receiving the following error when I was using the following code(given at the end). Error: evaluation nested too deeply: infinite recursion / options(expressions=)? I feel that since the function Grx is recursively related, perhaps making the code too complicated too handle. Can anyone let me know if

Dear folks. I am using smbclient 4.2.10 version (the one packaged for OEL 6, samba4-client-4.2.10-15.el6.x86_64), and observing a weird behaviour of the tool. I've got a Linux local directorio, say /tmp/eraseme, with a couple of subdirectories in it, say a and b, each one containing a dummy file, say a/AM.xls and b/AT.xls If I run: smbclient -d 30 -l /var/log/samba -m SMB3 -W

Two questions: First, what is R's maximum recursion depth (for function evaluations)? Is the value stored in a variable? Can the value be modified? Second, I've hacked out a function to take a matrix (array) of data and return another that is the same except it removes any duplicate columns. After doing this I discovered the unique() function and I tried to use it via apply() to do

Hello everyone, Can someone point me to some resources on managing data in R and/or S-plus? I have started using R more and more often in my work and I really like it. But, managing data is very different in R and S-Plus than in other packages that I am accustomed to. I know that it is an option to use different workspaces for different projects or to store all objects as source and read them

A while ago I asked about data management approaches in R. I was asked by several people to post a summary of the responses and alas I am just getting around to doing it. I received several comments, both on and off list. Below is a compilation of these responses. Hope this is as helpful to others as it was to me. Best, Brett 1.

I am creating a web-based gui to provide searching of files shared via SMB on a local network. It goes through and finds each computer, its shares, and its files using smbclient. Currently, a nasty (and incredibly slow) set of loops in php recurses the directories on each share using a smbclient call for each directory up to a set depth. I know for a fact of several computers on my LAN with

Hello all, To anyone who is interested, I'm trying to learn a bit more about developing applications in R with user interfaces. I've been playing around with gWidgets to develop a model building interface. I'd appreciate any comments, suggestions, or guidance on how to better structure my R code and organize the programming task. In addition, any suggestions for features and
