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? Thanks. David. -- View this message in context: http://r.789695.n4.nabble.com/Side-by-side-strip-charts-tp4636399.html Sent from the R help mailing list archive at Nabble.com.
Hi, Arnold, looking at the example section of ?stripchart may help you.

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: pd.mes at cbs.dk Priv: PDalgd at gmail.com
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?
Thanks.
