Hi all, Below is a URL for an editorial published today in our local newspaper, the Minneapolis StarTribune. It was originally published in the Washington Post a couple of days ago: http://www.washingtonpost.com/wp-dyn/content/article/2005/08/29/AR2005082901444.html but that site requires registration. The 'Strib" site seems to be open for the moment:

Hi, I would like to draw a pie chart. I've already tried out the standard pie-function in the GRAPH-package. My question: is there any 'better' function or package to draw a pie chart. For example I would like to draw a 3D pie chart. Dietrich Tissen

Dear R user group, I wish to plot small pie-charts to specific coordinates in a e.g. scatter-plot: E.g.: > plot(rnorm(100),rnorm(100)) > points(1,1,col="red",cex=4) -> I wish to put pie(c(2,3)) at the position of the red circle... How can I do this efficiently? Thanking you and wishing you a wonderful Sunday! Georg. ************************** Georg Ehret Johns Hopkins

Hi all, Could you please help me? I am looking for books/pointers/resources/tutorials on visualizing complex/big data and on understanding multivariate relations in complicated data. More specifically, we have categorical variables and are interested in how to visualize the categorical data and visualize data conditioned upon categorical values. Could anybody please give me some pointers?

Hi- I am trying to plot a matrix of categorical values across time using color to represent each individual factor. For example: 1982 1983 1984 1985 1986 1987 1 19 19 68 68 19 19 68 2 68 68 19 19 68 68 19 3 26 26 34 34 26 26 26 4 57 34 57 57 34 57 34 5 34 57 26 26 57 34 57 6 28 28 28 28 28 58

...he edition which I have) of Minard's graphical representation of what happened to Napoleon's army in the course of its advance on, and retreat from, Moscow. An impression of the original can be formed from the rather small version displayed on Tufte's website at the top of http://www.edwardtufte.com/tufte/posters The version in the book is much clearer. Here we see the two aspects of "intuitive" and spatial perception, and textual/numeric "analytical" perception, happily combined on the one display in such a way that the two interact richly.
