I'm having difficutly getting variables into a trellis panel function.
Specifically
I have a function that uses the "panel.loess" function. I would like to
be able to
change the values of the span, degree and family variables, but haven't
been able
to do so. All of the examples I have found always have these "hard
wired". A small
portion of my function follows. The span, family and degree are carried
into the
function in the original call.
Any help greatly apprecaited.
thx
bob

panel.loess(x,y,span=span,

else
panel.xyplot(x[order(x)],y[order(x)],type="l")},

)
)
