How to change coordinate grid in ggplot2 package in R language?

Question

R

I build a coordinate grid on the graph using the function coord_cartesian(), but I don’t know how to change the number of sections on a particular axis. It seems to be possible with the help of xaxp, yaxp, but either I'm doing something wrong, or it's not intended for this. But still, how to change the number of sections?

Answer 1

It is not necessary to change the grid, but the number of sections of the axes.
This is a parameter breaks.
This code

ggplot(data = mtcars)+
        geom_point(aes(x=mpg,y=hp))+
        theme_bw()

produces the following graph
, let's say we want the divisions on the x-axis to step through 1, not through 5.
Then we change the code as follows

ggplot(data = mtcars)+
        geom_point(aes(x=mpg,y=hp))+
        scale_x_continuous(breaks = 10:35)+
        theme_bw()

which gives the desired result
