Customizing Dose Response Curves in R with ggplot2's geom_ribbon
Here is a code snippet that addresses the warnings mentioned: library(ggplot2) # Assuming your dataframe is stored as 'df' ggplot(df, aes(x = dose, y = probability)) + geom_ribbon(data = df, aes(xintercept = dose, ymin = Lower, ymax = Upper), fill = "lightblue") + scale_x_continuous(breaks = seq(min(df$dose), max(df$dose), by = 1)) + theme_classic() + labs(title = "Dose Response Curve", x = "Dose", y = "Probability") Note that I’ve removed the y aesthetic from the geom_ribbon layer and instead used ymin and ymax to specify the vertical bounds of the ribbon.
