If you want lines that only span a portion of a plot
Try:
library(ggplot2)
ggplot(mtcars, aes(mpg, qsec, colour = as.factor(gear))) +
geom_point() + geom_smooth(method = lm, se = FALSE)
You probably will have to melt your data to get into the right format.

Hi all,
I'm struggling with the display of several regression lines (with different
colors) on the same plot.
I manually drew what I'm trying to do with 8 lines (see attached).
Any thoughts for a code will be very much appreciated.
Thanks
Armel
