Hi, I am trying to create what are called "spider diagrams" in the geochemical literature using R. A spider diagram is basically a plot of the atomic number versus the concentration on a log scale. Lines are drawn from each atomic number for each sample. Right now, my data frame looks like: SAMPLE SITE V3 LA.NASC LAATNUM CE.NASC CEATMNUM 1 1A:001

Does any one have a sample code for a Spider Plot as attached? Thanks, Xing

Dear all, I was wondering if there is a simple way to avoid printing the multiple cross-validation automatic output to the console of recursive partitionning functions like rpart or mvpart. For example... > data(spider) > mvpart(data.matrix(spider[,1:12])~herbs+reft+moss+sand+twigs+water,spider,xv="1se",xvmult=100) *X-Val rep : 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Dear R community, I am analyzing plant communities with the function mvpart, using a dissimilarit matrix as input. The matrix is calculated with the funtion gdist. fit <- mvpart(gdist (ba12[,18:29], meth="maximum", full=TRUE, sq=F) ~ beers + slope_dem + elev_dem+ plc_dem + pr_curv+ +curv+max_depth+doc_rocks+ abandon+land_use+ca_old, data=ba12, xv="p") This

Hi all, On a related topic to Web spidering, I would like to solve a problem of internally spidering and saving a Rails application from within rails. The goal is to spider and save each resource in a site to a filesystem friendly structure /many/things/1?page=3 -> many_things_1_page_3.html or /many/things/1?page=3 -> many/things/1_page_3.html If a redirect is created

Dear all, I'm getting an error in one of the stock examples in the 'mvpart' package. I tried: require(mvpart) data(spider) fit3 <- rpart(gdist(spider[,1:12],meth="bray",full=TRUE,sq=TRUE)~water+twigs+reft+herbs+moss+sand,spider,method="dist") #directly from ?rpart summary(fit3) ...which returned the following: Error in apply(formatg(yval, digits - 3), 1,

Hmmmm, not quite statistics, but can R do spider plot like shown in http://seamonkey.ed.asu.edu/~behrens/asu/msms/student/recent_vis/spider.html or http://www.caesarsystems.com/Technica/spiderPlots.htm Thanks for any hints, Mathias -- virtual earth Mathias Picker Gesch?ftsf?hrer Gesellschaft f?r Wissens re/pr? sentation mbH

Is there an R function to generate a radar or spider graph from a table - e.g. radar(table(x)) or some such? ================================================== Isaac T.

I was reading this post http://forum.winehq.org/viewtopic.php?p=45535&sid=6957add8af3402a8afa68d8527121e2d and others like it looking for a way to make the content in the WINE window look larger. I mean to look like 800x600 resolution when the monitor settings is at 1024x768. So, I have typed this on the command line: Code: wine explorer /desktop=spider,800x600 spider.exe or wine explorer

Hi, Is the stars command in the base package or do I need to download? I am looking to make star/radar/spider charts. Thanks!

First of all, I really like R! Still being a newbie, I find things (the difficult ones) to be very simple. Alas, some 'simple' things still escape me. (Maybe the tutorials are often too much focused on the 'difficult' items??) Here comes my 'problem', over which I have sweated for the last 2 hours: My data are of a matrix 10x31, Likert Scale (1-5). 10 questions, 31

Hello all, I was just wondering if anybody knew whether mechanize is supposed to be thread-safe or not? I didn''t really find any information about it anywhere. I''ve been getting a strange error in protocol.rb when I run a script that uses mechanize in a multi threaded fashion, but not with a single thread. I''m trying to write a spider that does multiple gets in

I'm new to R - and trying to create a plot similiar to the spider plot at http://www.statgraphics.com/eda.htm#radar . I can't figure out several things... most of which I would think would be straightforward.... How can I change the lines for each series plotted instead of creating a filled area? How can I get the labels for each of the radial axes at the outside of the plot

I hope this day finds you well. I need to generate Spider charts (aka radar charts) , and am using Gruff to do so. How can I show lines and axis numbers on a Spider chart? Here''s what I''m trying to make: http://img.skitch.com/20080925-m573hhdy4n4x6i92s17knjqjeg.jpg How can I have those 0 - 100 numbers, and the concentric cirles in the graph? Joe -- Posted via

Hi all, I have encountered a problem which appears to have defeated my (admittedly nascent) R skills. I want to draw a spider plot with many cases (just over 300). I am primarily interested in the difference between 4 categories of cases, and want to display them as different colors. the col.stars parameter does not change the color of the lines (which I'm after), but fills the stars in

Hi, After refactoring my site to have smaller controllers, I would like to spider test my site to find any broken links. Is there a way to do this with functional tests? Maybe regular expressions to find links and then follow them? Has anyone tried this or have a function they could share? Thanks, Peter

Dear All, I have a question regarding the output of survfit() when I supply a Cox model. Lets say for example: library(survival) fit <- coxph(Surv(time, status == 2) ~ factor(spiders), data = pbc) fit # HR for spiders is significant newdata <- data.frame(spiders = factor(0:1)) sf <- survfit(fit, newdata = newdata) sum.sf <- summary(sfit, times = c(2000, 2500, 3000)) # survival estimates for the yes/no spiders # and the 3 follow up times sum.sf$surv # corresponding...

Hello all, I'm having difficulty with setting up a mixed model using lme in the nlme package. To summarize my study, I am testing for effects of ornamentation on foraging behavior of wolf spiders. I tested spiders at two different ages (penultimate vs. mature) and of two different phenotypes (one species tested lacks ornamentation throughout life [non-ornamented males] while the other acquires ornamentation upon maturation [i.e. brush-legged males]). I tested a sample of brush-legged and no...
