I have a data that looks like this: http://dpaste.com/88561/plain/
And I intend to create multiple density curve into one plot, where each curve correspond to the unique ID. I tried to use "sm" package, with this code, but without success. __BEGIN__ library(sm) dat <- read.table("mydat.txt"); plotfn <- ("~/Desktop/flowgram_superimposed.pdf"); pdf(plotfn); sm.density.compare(dat$V1,dat$V2, xlab = "Flow Signal") colfill <- c(2:10); legend(locator(1), levels(dat$V2), fill=colfill) dev.off(); __END__ Please advice what's the right way to do it or if there is alternative way to do it? I am trying to get this kind of figure: http://img524.imageshack.us/img524/2736/testl.png - G.V. ______________________________________________ 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.
