[R] How to add a line on the boxplot
Hi, I have a data frame, df=rnorm(1000) dim(df)=c(100,10) And i can get the boxplot, boxplot(data.frame(df)) So how can add a line (aline) on the existing boxplot,eg, aline=apply(df,2,max) Thanks in advance.

Thanks The first method,i get many lines,using the second,i get segments.I actually need one line with y coordinate defined by aline,x along the boxplot.

If not, please explain in another way how you want to arrange those 10 values and make lines from it.
