Putting two lm+pred datasets into one ggplot

[nirgrahamuk]

something like this ?

Can I plot 2 data subsets (regression line with confidence interval) in 1 graph?

example of linear model over 3 sets of species in iris data library(ggplot2) ggplot(data= iris , mapping = aes(x = Petal.Width, y = Petal.Length, color=Species)) + geom_smooth(method='lm', formula= y~x) [image] Edited::as replied to wrong post.
