Plotting series marked with a symbol on every nth data point, preferably in ggplot...
...ver, there are so many symbols, that they overplot and
the whole plot is unreadable once again. I am looking for advice on
how to make a plot with continuous lines and symbols appearing at
every nth point. An example of this problem and a solution in SAS can
be found here:
www2.sas.com/proceedings/sugi26/p072-26.pdf
The obvious solution would be to extract the n-th point from the
dataset and overplot as a new line with symbols, but this does not
change the legend, does it? How can I then have a line+symbol in the
legend represent my curve?
Now, ideally I would prefer a solution in ggplot, because...

Hi,
this is not a new doubt, but is a doubt that I cant find a good response.
Look this output:
> m.lme <- lme(Yvar~Xvar,random=~1|Plot1/Plot2/Plot3)
> anova(m.lme)
numDF denDF F-value p-value
(Intercept) 1 860 210.2457 <.0001
