Hi Raphael,
Not sure about lattice but the ggplot2 packge has some straight forward
examples.
see bottom figure on this page http://had.co.nz/ggplot2/scale_date.html
plus http://had.co.nz/ggplot2/scale_datetime.html
Dates need to be POSIXct
?POSIXct

Subject: [R-sig-eco] Help plotting time series from multiple years?
Message-ID: <4db31537.1020...@sccwrp.org>

I would like to make a lattice plot of a variable by date from multiple
years, where each panel is a different station, and each year is
represented by a different line color. My data look something like this:
StationDateScore
Site15/19/2009552
Site16/23/2009578
Site18/5/2009604
Site19/15/2009618
Site14/13/2010610
Site15/11/2010618
Site16/15/2010118
Site17/20/2010592
Site19/1/2010590
Site25/18/2009628
Site26/22/2009590
Site28/4/2009628
Site29/16/2009610
Site210/20/2009618
Site24/15/2010200
Site25/11/2010118
Site26/15/2010217
Site27/20/2010479
Site29/1/2010353
I feel like this should be simple enough to do with Lattice using
xyplot, but I'm not having much luck. Any suggestions?
Thanks!
