similar to: Bubble Plot with Pie Charts

Hello, I am currently trying to show the abundance of two species of zooplankton within the North Sea as pie chart bubble plots. I followed Werner Wernersen's advice in R help (http://finzi.psych.upenn.edu/R/Rhelp02a/archive/48644.html) and used Paul Murrell's paper "Integrating Grid Graphics Output with Base Graphics Output" (in R News) to try and do this (using the gridBase

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

Dear R-Community. I am trying show pie charts on a graph. To be precise, I have series of catch calues by species by geographic (5 deg by 5 deg) regions. I want to draw circles (actually pie charts showing the proportion of the catch in each area) so that I have a graph of catch by species by geographic area! I know there is the < symbols(dat$lon,dat$lat,circles = dat$sp1, add=TRUE) > but

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

Hey, i'd like to compose a clock-like looking plot composed out of two circles, each showing the length of a period (to compare them). first, to do so, it looked the easiest by using pie(), just puting multiple pie-charts over each other. the problem is that once the second pie is drawn, it replaces the first one. does anybody know how to add a second, smaller pie over an existing one,

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 , 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]]

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

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, 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

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

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

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

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

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",

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]]

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

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.

Hello, I hope somebody can help me. I'm using the R-comander with library(Rmcdr). Using the menu, I added an new data-matrix . After I wanted to draw a pie chart, but the problem is, that the pie chart menu is blinded out. In the concerning variable column, there are no NA -Value (is.na) . Anybody has a solution? thxs Iksmax
