proportional symbol map ggplot
...ame proportions as the scaled variable. Hereby an example we found on http://www.r-bloggers.com/bubble-chart-by-using-ggplot2/ . In this example we see the proportions of the symbols' area are different from the proportions of the scaled variable: crime <- read.csv("http://datasets.flowingdata.com/crimeRatesByState2008.csv", header=TRUE, sep="\t") p <- ggplot(crime, aes(murder,burglary,size=population, label=state)) p <- p+geom_point(colour="red") +scale_area(to=c(1,20))+geom_text(size=3) Example: proportion population Pennsylvania/Tennessee= 2.003 propor...

Preferred way to create bubble plots?
I have to create a number of bubble plots, and am wondering what methods folks prefer for this task. I've been experimenting with the symbols() function, with text() to provide plot labels. Any opinions on the relative merits of this method versus others? One criterion would be the ability to fine-tune the placement of text labels. I would like to use lattice, but haven't found a way to

Represent point size according to frequency
Hello! I would like to make a scatterplot of my data, but the problem is that several points have the same x and y values and are represented as only one point. I wonder if there is a way to represent the data points, but with point size representing the frequency of the depicted x-y value? Thank you! -- View this message in context:

Combined Marimekko/heatmap
Hi all, I'm trying to figure out a way to create a data graphic that I haven't ever seen an example of before, but hopefully there's an R package out there for it. The idea is to essentially create a heatmap, but to allow each column and/or row to be a different width, rather than having uniform column and row height. This is sort of like a Marimekko chart in appearance, except that
