Function Errors
Missing ggplot2 aesthetics
Matches: geom_.* requires the following missing aesthetics
WHAT THIS ERROR MEANS
A ggplot2 geom layer requires certain aesthetic mappings (like x, y, fill, color) that you haven't provided.
HOW TO FIX IT
1. Add the required aesthetics inside aes().
2. Check the geom's documentation for required mappings.
3. Aesthetics can be set in ggplot() globally or in the specific geom.
CODE EXAMPLES
BAD — THIS CAUSES THE ERROR
ggplot(df) + geom_point() # missing x and y
GOOD — CORRECT APPROACH
ggplot(df, aes(x = weight, y = height)) + geom_point()
