This is a thread for Jumping Rivers "Best Practices with R" attendees to practice preparing and sharing code questions using minimal reproducible examples (reprexes). There is no need to respond to these questions, as we're just practicing.

I'm trying to create a plot with yellow points, but the graph has red points.

library("ggplot2")
data(penguins, package = "palmerpenguins")
ggplot(penguins, aes(bill_length_mm, bill_depth_mm)) +
  geom_point(aes(colour = "yellow"))
#> Warning: Removed 2 rows containing missing values (geom_point).
