Side by side strip charts

 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. Any ideas? Thanks. David.

 Hi, Arnold, looking at the example section of ?stripchart may help you.   Hth  --  Gerrit On Thu, 12 Jul 2012, darnold wrote: > 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.

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. -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: [hidden email]  Priv: [hidden email] ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.

Re: Side by side strip charts

 OK, got this far: x1 <- round(rnorm(10,60,3)) x2 <- round(rnorm(10,65,3)) x3 <- round(rnorm(10,70,3)) stripchart(list(sample1=x1,sample2=x2,sample3=x3),            method="stack",            pch=4,            offset=1/2,            col="blue",            lwd=2,            las=1) Any ideas on how to get an axes drawn under each one as in the image?
