Re: [R] HELP boxplot for time class
Thanks a lot Gabor, now I could finally plot the as time data. I just have one more question, and I hope it is the last. In the script of the boxplot, bp - boxplot(as.numeric(skiers$start), yaxt = n) axis(2, bp$stats, times(bp$stats), las = 2, cex.axis = 0.5) I have been trying to add a main tittle and xlab, ylab with no succes. Where I am supposed to type: main=skiing starting tour and so on Thanks a lot!!
