Hi,
I'm trying to create a plot using pair.
Currently I'm doing the following
pairs(~mpg + hp + wt , data=cars, labels = c("Miles per
Gallon","Horsepower","Weight"),pch = c(24,25)[unclass(cars$tr + 1)],
bg = c("red", "green3")[unclass(cars$tr + 1)],panel=panel.smooth)
for the attached dataset. However,instead of using panel.smooth I
would rather have two fitted regression lines for each car
transmission type (cars$tr).
Is this possible?
Thank you
Ben
