similar to: Subject: Re: how to include bar values in a barplot?

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: I recall as a child

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

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

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' , 'hawaii',

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. I've spent a

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

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

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 check it out here:

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

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

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: "Who would have thought we

Have you read the books by Cleveland? His experiments show that most people do better estimating things and comparing things on a linear scale rather than looking at angles and areas (also see http://biostat.mc.vanderbilt.edu/twiki/pub/Main/StatGraphCourse/graphsco urse.pdf) With a dot chart you can set the axis to go from 0 to the total of all groups (see the example I sent before, it could

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: \name{Minard} \Rdversion{1.1} \alias{Minard} \alias{Minard.cities} \alias{Minard.troops} \alias{Minard.temp} \docType{data} \title{ Data

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

[Environment: WinXp, R 2.9.2, all packages up to date; building under (StatET 0.8, eclipse 3.5.1) or from a batch file] I'm in the process of creating a package, HistData, on R-forge, containing interesting data sets from the history of statistics and data visualization.

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, Dieter -- Dieter Vanderelst

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. Faheem.

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.
