R code of this video:

set.seed(23876382) # Create example data
x ＜- rnorm(100)
y ＜- x + rnorm(100)
data ＜- data.frame(x, y)

install.packages("ggplot2") # Install & load ggplot2 package
library("ggplot2")

ggp ＜- ggplot(data, aes(x, y)) + # Draw plot with stat_smooth line
geom_point() +
stat_smooth()
ggp

ggp_data ＜- ggplot_build(ggp)$data[[2]] # Extract information about plot
head(ggp_data) # Head of information data

ggp_fit ＜- ggplot(ggp_data, aes(x, y)) + # Redraw stat_smooth line
geom_line()
ggp_fit
