Hi, all, Let's say I have some time series data--10 subjects measured 20 times--that I plot as follows:
library(ggplot2) dat <- data.frame(subject=as.factor(rep(1:10, each=20)), time=rep(1:20, 10), measure=as.vector(replicate(10, rnorm(20, mean=runif(1, 0, 15), sd=runif(1, 1, 3))))) p <- qplot(time, measure, data=dat, colour=subject, geom="line") p What would be the preferred way to add a single label to every line? For instance, labels might be most readable at the beginning, end, or peak (max value) of every line. I could do: p + geom_text(aes(label=subject)) But this gets messy when the labels are longer than single digits; instead, I want a single label per line. I suppose a dataset could be put together composed of single points and labels and then layered atop p, but perhaps there is a more direct method. Any help would be greatly appreciated, Jeff. ______________________________________________ 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.
