Dear users This is a message I was directing to Harold Baize but because I pressed the wrong button the message got lost grrrr!!!
So I’m doing it all over again: Lets suppose I have three batches of data: a <- rnorm(50,2500,300) b <- rnorm(50,3500,250) c <- rnorm(50,4000,200) # Now I want to plot them as boxplots and violin plots require(vioplot) vioplot (a,b,c, horizontal=T, col=“white”) boxplot (a,b,c, horizontal=T, col=“white”) As we know boxplot show the least-greates values, lower-upper quartiles, the mean, and outliers (when present). However, for some data is not important the MEDIAN but the MEAN. Also, it is more relevant to show ERROR BARS instead of quartiles. So, how could I see (for the batches of data I introduced above)… 1. a boxplot showing the MEAN and the SD instead of the lower/upper quartile? 2. a boxplot showing the MEAN and the STANDARD ERROR OF THE MEAN instead of the lower/upper quartile? 3. a boxplot showing the MEAN and the 95% CI instead of the lower/upper quartile? (I think in all these cases is preferable to have visual access, or to have the line that shows, the LEAST and the GREATEST VALUES.) In other words, that the ERROR BARS (95% CI, SD, SE) proposed here take the place of the boxes usually used to represent the lower/upper quartile. Now, the big question, is all this jazz possible to be implemented in violin plots as well? How could that be done?
