[R-sig-Geo] Solid and dashed line.

[Ashim Kapoor]

Dear Enoch,

Would this suffice for you ?

library(ggplot2)

ggplot(mtcars, aes(x=wt, y=mpg)) +
  geom_point( color="black")+
  geom_smooth(method=lm, se=FALSE,
              color="darkred")

ggplot(mtcars, aes(x=wt, y=mpg)) +
  geom_point( color="black")+
  geom_smooth(method=lm, se=FALSE, linetype="dashed",
              color="darkred")

Note : I got these examples from :

Best Regards,
Ashim
