Dear All,
Using Splus 6.0 on a Windows 2000
machine
I am having a problem with the trellis
graphs using the code below
xyplot(hsi ~ wt |
vehicle,
prepanel = function(x, y)
prepanel.lmline,
xlab = "Weight",
ylab = "HSI",
panel = function(x,
y) {
panel.grid(h=0, v=
0)
panel.xyplot(x,
y)
panel.abline(lm(hsi~wt,na.action="">
},aspect = "xy")
There are 3 vehicles and the scatter plot for
these turns out fine however the fitted lines I ask for in the panel.abline it
plots the regression line for the first vehicle on all 3 plots.
Could anyone indicate how to stop this happening,
the same thing happens in the other not too dissimilar package.
Also in S-plus, but not the other package, one of
the vertical axes is not aligned properly on the graph, can this be remedied
also
Many thanks in advance
Guy
