Hi. first things first ... thanks for ggplot2.
Now my question. I'm using qplot to generate a plot as follows where X,Y,Z, A are columns in a dataframe. qplot(X, Y, data=XYDATA, color=Z, geom=c("point"), size=A) This works as expected. Factor A has three levels so there are three sizes of the point plot symbol. I understand that the factor levels are mapped to symbol sizes. However the sizes are too small for my liking. Is there any way I can specify the range of plot symbol sizes that factor A levels are mapped to? -- View this message in context: http://r.789695.n4.nabble.com/specifying-plot-symbol-sizes-in-qplot-or-ggplot2-tp2248217p2248217.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
