similar to: display two pie-charts

We regularly get questions about making pie charts, and frequently veer off into the philosophical and practical issues surrounding that form of data graphic: human perception of angles and so on. So while this isn't an R issue, I thought some of you might appreciate this brief discussion of the efficacy of pie charts: http://fakescience.tumblr.com/post/6042293374/understanding-pie-charts

Hi, I have a vector of data, that I group based on two factors via tapply. For each such grouping I would like to plot a pie chart. I can layout these pie charts in a matrix layout, correpsonding to the levels of the two factors. But I am getting stuck on how to label the rows and colums. My current approach looks like this: x <- data.frame(obs=sample(c('low', 'high'),100,

Hi there! I have seen that someone had this question some years before, but there was only a rough answer to it and I was wondering if actually someone was able to accomplish it or maybe even wrote a function... How do you make a bubble plot where you have pie charts instead of bubbles? I have a geographic map and need to plot attribute-sized pie charts representing a second attribute at

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 again! I put this question in another topics post before but I fear it might drown there. Is it possible to have transparent / alpha blended colors for pie charts? I am using the pies in a map of pies and those pies are sometimes overlapping so it would be great to see if another pie lies beneath. Thanks, Werner

Hi , I am looking to making a panel of pie charts fo some of my dritribution data . I was wondering if there is a way in any R package to write a small script to do so. Thanks, Amin [[alternative HTML version deleted]]

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

Hi All, I'm trying to find out a way to plot multi-panel pie charts. It may not be the best way to present data, but I would still need one. 1. Is anyone aware of some in-built script/function which can do this for me. I'm aware of one given in Deepayan's book, but anything apart from this? 2. I tried using Deepayan's script on following data set but it doesn't seem to work

I don't suppose it's possible to create a pie chart in R? I've got 1500 some odd elements in a frame that are valued at either -1, 0 or 1 and I'd like to find a reasonable way to represent the distribution graphically...any ideas? Joshua Gramlich Piocon Technologies Chicago, IL

Dear all, After going through the Lattice doc and R-help list and google, I got the feeling that there is no function in lattice or other package to compute a pie chart object of class "trellis". Although pie charts are obviously not considered optimal even in the pie() doc ;-) , pie chart trellis objects would be easy positioned e.g. over a map drawn with the grids package. Can

Hi, despite the fact that pie charts often fail, I'll draw them anyway (in a case were they are not fail ;-) ). Does anybody know a package/methods which can draw pie of pie or bar of pie charts similar to that in MS Excel? -- Kind regards, Mathias

Hi all, I've a problem with the size of the labels of my pie-charts when I try to write them to a postscript file. I need to increase the default size, so I change cex (see below). On screen this works fine, but cex doesn't seem to affect the postscript-file. Any suggestions? Thanks a lot, Daniel Copy/Past-example (will try to write to c:/temp!): labels <- c("I",

Hi, I've been investigating the ape package for a while, and I was wondering if it is possible to: - display the names of the internal nodes (from a newick tree) - plot a pie-chart on top of each of the internal branches in a phylogram plot Thanks in advance, Cheers, Albert.

Hey R'rs, So im sick of dealing with ESRI products and am looking to stream line a process i now use GIS to do using R. I have made a lot of maps using R but have not yet seen a map that puts pie charts within the map to help represent data like the attachment. http://r.789695.n4.nabble.com/file/n2318816/template1.bmp I found Tanimura et al. work "Proportional Symbol Mapping in

I am having trouble finding out how to adjust the position of labels on pie charts. For the small wedges, many of the labels overlap making it impossible to read. Is there any way to offset the labels so that they don't overlap? Adam Green USGS Patuxent Wildlife Research Center [[alternative HTML version deleted]]
