Thanks, Jim. The code works, but I don't understand why you use q1090 <- quantile(DF1$B, probs=c()), rather than DF1$A? Also, how to add a legend for both points DF1 and DF2?

Hi lily, Here is the first plot: plot(DF1$A,DF1$B,pch=19,col="red") meanA<-mean(DF1$A) meanB<-mean(DF1$B) points(meanA,meanB,pch=18,col="red") q1090<-quantile(DF1$B,probs=c(0.1,0.9)) library(plotrix) dispersion(meanA,meanB,q1090[2],q1090[1], intervals=FALSE,col="red") The same code will work for a second data frame, except that you would use "points" instead of "plot" and change the color. You may also have to...

Hi R users, I have a question about plotting. There is the dataframe below, while each row represents a record. If I want to plot on a A-B plot, i.e., x-axis represents A, while y-axis represents B values. However, I want to plot the mean value from records 1-10 as one point, while the 10th and 90th percentiles represent the error bars, such as one point in the attached example. I don't know
