Ggplot line and point. There are many different ways to use R to plot line graphs but the one I prefer is the ggplot geom_line function. Scale_shape_manual and scale_color_manual Use special point shapes including pch 21 and pch 24. And we get a nice scatter plot with paired points connected by line.

The code equivalent to above and more can be this few lines. Thus you just have to add a geom_point on top of the geom_line to build it. It makes the code more readable by breaking it.

This is a linear model fit so I use method lm. This can be one value or multiple values. Ggplotdf2 aesxdose ylen groupsupp geom_lineaeslinetypesupp geom_point ggplotdf2 aesxdose ylen groupsupp geom_lineaeslinetypesupp geom_pointaesshapesupp.
