Here are some plots

We often make plots in data science.

Here’s the tidyverse.

library(tidyverse)

Here’s a dataframe.

plot_df = 
  tibble(
    x = rnorm(100, mean = 1, sd = 2),
    y = 1 + 2 * x + rnorm(100)
  )

Here’s a plot. This seems to show

\[y_i = \beta_0 + \beta_1 x_i + \epsilon_i\]

plot_df |> 
  ggplot(aes(x = x, y = y)) + 
  geom_point()
