You can embed an R code chunk like this:

summary(cars)
fit <- lm(dist ~ speed, data = cars)
fit

par(mar = c(0, 1, 0, 1))
pie(
  c(280, 60, 20),
  c('Sky', 'Sunny side of pyramid', 'Shady side of pyramid'),
  col = c('#0292D8', '#F7EA39', '#C4B632'),
  init.angle = -50, border = NA
)

library(ggplot2)
ggplot(Orange, aes(x = age, 
                   y = circumference, 
                   color = Tree)) +
  geom_point() +
  geom_line() +
  guides(color = FALSE) +
  theme_bw()
