GGPlot2 Essentials for Great Data Visualization in R geom_hline : Add horizontal lines A simplified format of the function geom_hline() is : geom_hline(yintercept, linetype, color, size) It draws a horizontal line on the current plot at the specified ‘y’ coordinates : library(...
#with regression line ggplot(df, mapping = aes(x=x, y=y)) + geom_point(color="blue") + geom_smooth(method='lm', se=FALSE, color="red") 我想要插入像这样的密度曲线(只是朝相反方向):
adding regression line per group with ggplot2I'm not quite sure whether that's what you want, but have you tried the following?
ggplot(mapping = aes(x = price_per_unit)) + geom_histogram(bins = 100, fill = "midnightblue", alpha = 0.7) + # Add lines for mean and median geom_vline(aes(xintercept = mean(price_per_unit), color = "Mean"), linetype = "dashed", size = 1.3) + geom_vline(aes(xintercept...
