Hi, I'm looking for some ideas on how to reproduce the attached image in R. There are three samples, each of size n = 10. The first is drawn from a normal distribution with mean 60 and standard deviation 3. The second is drawn from a normal distribution with mean 65 and standard deviation 3. The third is drawn from a normal distribution with mean 70 and standard deviation 3. http://r.789695.n4.nabble.com/file/n4636399/IMG_1306.jpg Any ideas?
What an excellent homework exercise... stripchart() will do it if it gets a list() of vectors and you set the method= right. Notice that points won't stack unless exactly equal, so round()ing is required.
