I'm trying to wean myself off the very limited capabilities of Excel
and Oo.
Currently, I am trying to make a plot showing several values for 2
categories in a dot blot (see
http://www.nabble.com/file/p24538360/Picture%2B1.png Picture+1.png
except
that the x axis should contain the category not a number, which was
the only
way to coax Excel into displaying a plot like this). I started working
through some tutorials but the example didn't quite fit what I was
looking
for. The closest was the car and mpg example but it 1 value per name
whereas
I need several value per category. Does anybody know this of the top
of your
expert heads? This would be a great help. I already burned a few hours
without getting closer to the solution..
Something like so?
a <- rnorm(20, 10, 2)
b <- rnorm(20, 15, 1)
plot(jitter(rep(1, length(a))), a, ylim=c(0,20), xlim=c(0,3),
xlab=NULL, xaxt='n')
points(jitter(rep(2, length(b))), b)
axis(1, c(1,2), labels=c('Group 1', 'Group 2'))
Some points:
* plot(..., xaxt='n') -- suppresses plotting of xaxis (see ?par)
* I'm using jitter to add a bit of noise about the x vals so points
don't draw ontop of eachother
HTH,
