  1. You can't use abline with ggplot. Use geom_smooth with method = "lm" instead.

  2. You are missing a closing parenthesis ), as is evident by having the + symbol in the console, which means R is waiting for further input. In the script editor, while your cursor is on the last parenthesis, it is highlighting the parenthesis that it's closing.

  3. It's generally not recommended to use attach.

  4. You might want to read an introduction to ggplot and work through some examples.

To get to the plot you wanted, I would write:

ggplot(diamonds, aes(x = log(carat), y = log(price), col = color)) +
  geom_point() + geom_smooth(method = 'lm')
