Producing the Error
Here we will create dataframe with two variables and then try to plot with the incorrect place of aes().
R
library (ggplot2) # Create example data data <- data.frame (x = 5:1, y = 10:6) ggplot () + geom_point (data, aes (x=x)) |
Output:
Error: `mapping` must be created by `aes()`
How to Fix: error: `mapping` must be created by `aes()` in R
