Hi:
There are times when lattice is easier than ggplot2 and times when the
converse is true. This is a case where ggplot2 is easier to code once
you understand what it is doing. I'm going to try to reproduce your
lattice graph in ggplot2 as follows:
Dear Laurent,
Why not use "type="l""?
xyplot(value ~ time,
data=data.sim,
nr=100,
groups=essai,type="l",auto.key=list(columns=5))
You could also use more/better colours using RColorBrewer and/or
ColorRamp...
Cheers

Dear Laurent
for numeric x variables, you could try jitter:
xyplot(y~jitter(x,0.5))

Dear Laurent

Hi,
I like to use with xyplot (package lattice) the groups argument and
superpose.symbol to compare several curves. But, when there are a great
many points, the symbols are very close and the graph becomes
unreadable. Would there be an argument or a tip not to draw all the
symbols, for exa
