panel.linejoin groups
...datalogger organizes the output like this:
Date A1L A2L A3L
2005-07-14 22:00 208.1 -178.5 196.8
2005-07-14 22:10 207.9 -184.3 200.0
Now I'm having trouble plotting A1L, A2L, A3L on the same plot as a
function of Date. I thought I would try panel.linejoin, like so:
xyplot(data=redox2, A1L + A2L + A3L ~ Date,
panel=function(x,y,...){panel.linejoin(x,y,horizontal=F,col=1,...)},
scales=list(x=list(tick.number=10)))
But of course, what I get is the mean of the measurements from those
three columns plotted as one line, when what I want is a separate line
for each column of dat...
