distinguish regression lines in grouped, black and white lattice xyplot
...I cannot think of a solution right now:
if got a lattice xyplot in black and white and a grouping variable
with many (more than 8
values) and I plot it as regression lines (type="r"), just like this
one (not reproducable but that's
I guess not the point here):
xyplot(log(AGWB) ~ log(BM_roots), data=sub_agwb_data, groups=species,
type="r", lty=c(1:6),panel=allo.panel.5)
The problem is that I've got 26 different values for the grouping
variable species and only 6 default values for the line type
lty (and according to the par {graphics} help page customizable to up
to 8 di...

package lmodel2: p-value RMA fitting?
...ke in the output of lm?
Sorry for bothering everybody with this, well, probably rather idiotic
question, but I don't know where to
continue from this point...
Thanks,
