Hello -

So I am trying to use ggplot2 to show a linear regression between two variables, but I want to also show the fit of the line on the graph as well.

 I am using ggplot2 for other graphics in what I am working on, so even though this would be a fairly easy thing to do in Excel, I would prefer to do it in R to keep my look and feel, and I think ggplot2 is just cooler.

Here is a sample script of what I am trying to accomplish:

df<-NULL
df$x<-rnorm(100)
df$y<-rnorm(100)
df<-data.frame(df)

ggplot(df, aes(x=x,y=y))+geom_point()+geom_smooth(method=lm)


# would like to be able to showr squared and slope/intercept of lm
