Hello, I have the following data frame, using lattice and qqmath, how do I display the quantile plot (e.g distribution = qunif), but highlight the f==TRUE and f==FALSE differently?
library(lattice) pp <- function(n) ((1:n)-0.5)/n x=data.frame(x=runif(20),f=sapply(runif(20),function(r) r>0.5)) I would like a single curve, the following example displays two curves. qqmath(~x,groups=f,data=x,distribution=qunif,f.value=pp) Thank you Saptarshi ______________________________________________ [email protected] 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.
