perception of graphical data
Hello,
I apologize that this is off-topic. I am seeking information on
perception of graphical data, in an effort to improve the plots I
produce. Would anyone point me to literature reviews in this area? (Or
keywords to try on google?) Is this located somewhere near cognitive
science, psychology, human factors research?
For example, some specific questions I have are:

for loop
Hi,
I need your help.
I have a vector of numbers reflecting the switch in the perception of a
figure. For a certain period I have positive numbers (which reflect the
perception A) then the perception changes and I have negative numbers
(perception B), and so on for 40000 iterations. I need to take the rate of
this switch for my analysis. Namely, I need a new vector with numbers which
reflect how

Warned about these "three little maids"...
Greetings all:
Newcomer to R as I work on learning it to transfer my college classroom
stats training to something more useful and accurate then that spreadsheet
from Redmond which shall remain nameless.
I'm running v2.6.2 on a Win XP Home system that I keep up to date with all
the called for patches. Haven't added much to the basic install other than
the bits and bobs needed to run

mapping states with colors
Hi folks,
I'm just learning how to use maps. As an initial foray, I'm mapping the
states that have "duty to retreat" (blue) and "stand your ground" (red)
self-defense standards. Here is my extremely naive script:
dtr <- c('alabama', 'arizona', 'conneticut', 'delaware', 'dist of columbia'

Colours for 3-way probabilities
Are there any R functions for creating palettes for three-way data?
For example, election maps for three parties where pure red, blue, and
green show 100% for the Red, Blue, and Green parties respectively,
magenta shows a 50-50 Red-Blue split with 0 for the Greens, cyan a
50-50 Blue/Green split with no Red votes and so on, with grey, black
or white at a 1/3,1/3,1/3 split vote.

General CentOS 5.1 (or Gnome) instability?
I've been a big fan of CentOS for a while, and didn't have many
issues with CentOS 4.X over the past few years. However, since
moving to CentOS 5.1 a few weeks ago, I have received more problem
reports from my users than in the last year and a half on CentOS
4.X. I've previously reported the problem with gnome-terminal
crashing (and since there is a single gnome-terminal

Getting started with R
I've got a background in computer science & have been using Linux for
nearly a decade. I'm working on a Ph.D. in education and technology
and I essentially live in emacs and do all of my writing in LaTeX.
To me R seems like the perfect stats package. Unfortunately, the
learning curve is killing me. I feel like that if I'd waded through
pulling down menus in SPSS or SAS I could

Machine learning teaching for Data Science Retreat
Hi all,
We are preparing for a future batch, and we may be shorthanded for
teaching. R is our programming language of choice.
Data Science Retreat (DSR: http://datascienceretreat.com) sits at Microsoft
Ventures offices in Berlin Mitte. We have chief-data-scientist mentors and
a pretty exhaustive program on machine learning + data science. You can

hi,?
I'm working on a research project where we're looking at the changing resonances in femur bones during hip replacement operations. basically, I've got a spreadsheet with one column listing frequencies in 5Hz bands and 3 columns showing the amplitude of that frequency when the bone is loose, medium to tight (referring to the tension of the reamer/chisel creating a cavity for the

Function recommendation for this study...
Hi,
I'm not used to thinking along these lines, and wanted to ask your advice:
Suppose you have a sample of around 100, consisting of patients according to
doctors, in which patients and doctors are given a questionnaire with
categorical responses. Each patient somehow has roughly 3 doctors, or 3
rows of data. The goal is to assess by category of each question or DV the
agreement between

Diamond graphs
I apologise for starting a new thread, but we had a mail problem and I
don't have the original message to refer to.
Someone mentioned the new "Diamond Graphs" invented at Johns Hopkins.
I haven't see the August 2003 issue of The American Statistician yet,
but I _have_ read the press release.
The press release is a bit of a stunner. I quote:

Adding percentage to Pie Charts (was (no subject))
Have you read the books by Cleveland?

Documenting related data sets
Say I want to include the data from Minard's march on Moscow graphic in
a package. They consist of
three data frames, Minard.troops, Minard.cities, Minard.temp.
I've determined that I can document them all in one .Rd file, Minard.Rd,
that starts:

\Rdversion{1.1}
\alias{Minard}
\alias{Minard.cities}

Invert Likert-Scale Values
Hi!
I am using R to process some community survey data. Several item responses are recorded via a 7-point Likert-Scale. As I have coded the responses, 1 represents high agreement, and 7 high disagreement. This of course impacts the coefficients in a linear regression (of example agreement to self-perception measures on housing satisfaction). For some purposes, in order to make the coefficients

Kruskal's MDS results
Dear List,
I'm trying to interpret the results of the Kruskal's Non-metric Multidimensional Scaling algorithm (isoMDS, MASS package).
The 'goodness of fit' is reported as "The final stress achieved (in percent)".
What does this mean exactly? I've tried to google for an answer but I've not come up with a definitive answer.
Regards,

compile error with C code and standalone R math C library
Dear People,
I just went back to an old piece of C code. On trying to compile it with
the R math standalone C library I got the following error. Can anyone
enlighten me what I am doing wrong, if anything? C file (rr-sa.c) follows.
I'm on Debian sarge. I'm running R version 1.8.1. Gcc is version
3.3.1.
Thanks in advance.

Setting up asterisk with current PBX?
We currently have a Toshiba Perception EX and I would like to start
moving toward VOIP. Is there anyway we can run these two systems in
parrallel? Better yet, is there anyway we can run fully on asterisk
using the current PBX hardware? The current PBX has a mix of analog,
digital and electronic cards in it. I tried to google for advice but
I didn't find anything that pertained to this.
