Changing the Picture with ggplot2

[zsl3713]

I wanna use R to complete the quantile regression and then draw the picture by Plot function.

BUT I wanna one plot just like the picture1.

I have no idea how to complete the picture in plot function or gglot2

Thanks for your help!

library(quantreg)

fit1 = rq(TQ ~ PACE + ORTG + DRTG, tau = c(0.10,0.25,0.50,0.75,0.90), data = ZSL)

plot (fit1)

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue.
