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 all, I am looking to create a pie chart from a given column in a .csv file. My class variables are as follows: entry_type, uniquekey, types, title, url, abstract, journal, author, month, year, howpublished So say I want to export a pie chart that groups together all entries under 'types' e.g. 3 x statistics 2x education etc. Im looking to have a piechart represent this

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

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

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]]

Hi R users, I am wondering if it there is any R's function helping integrate venn diagram and pie chart to compare two related datasets. I know the package limma(bioconductor) has something built-in for making venn diagram, but I guess it would be very painful to use line and text to specify the proportions in the fashion of pie chart . Thanks in advance, Kevin Chang -- View this

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

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

With a pie chart pie(c(11, 15, 16, 29, 31)) how can I generate labels for the chart, such as orange: 11 green: 15 blue: 16 red: 29 purple: 31 rather than the default labels that are drawn automatically 1 2 3 4 5 -- Mark Polishook, D.M.A. Technology Coordinator Morehead Hall, Rm 132 Center for Academic Advising and Adult Learning Montclair State University Montclair, NJ 07043 (973)-655-7114

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 have a list of IPI gene IDs.

Hello! It's a shoot in the dark, but I'll try. If one has a total of 100 (e.g., %), and three components of the total, e.g., mytotal=data.frame(x=50,y=30,z=20), - one could build a pie chart with 3 sectors representing x, y, and z according to their proportions in the total. I am wondering if it's possible to build something very similar, but not on a circle but in a square - such that
