I want to add abline() to the scatter plot , blow code only can return the scatter plot (the abline can’t show). Anyone can help on this ? Thanks! library(tidyverse) model <- lm(mpg~ disp,data=mtcars) abline_data <- data.frame(intercept=coef(model)[1], slope=coef(model)[2]) mtcars %>% ggplot(aes(x=mpg,y=disp))+ geom_point()+ geom_abline(data=abline_data,aes(intercept=coef(model)[1] ,slope=coef(model)[2]), color="red",size =6) >Solution : Switch your independent/dependent variables in the ggplot(aes())… Read More Add abline in ggplot2 which data from lm() result failed

I want to assign the means of x and y to a scatterplot in R without ggplot, just basic R. However, in the way I try (using abline), it does not illustrate the lines in the plot. I already had to do another task earlier, hence the slightly longer code. I tried using abline for… Read More Mean in Scatterplot not illustrated
