How to avoid broken line in ggplot2

Question

I try to plot a graph in R using the ggplot2 package. Let's assume I have the following data:

df1<-data.frame(xpos=c(1,2,3,4),ypos=c(0.222,0.222,0.303,0.285))

Now, I want to plot a simple line graph:

ggplot(data=df1, aes(x=xpos, y=ypos)) +
  geom_line()+
  geom_point()

Now, when I adjust the y-axis:

+scale_y_continuous("Y rates upd", breaks=seq(0,1,0.2),limits=c(0,1))

The lines get "broken"

It is not entirely clear what you mean with "broken". Is it the missing interpolation of the pixels? This is an issue of the graphical device. If you save the plot as PDF it should look more smooth.

That's dependent upon your graphics device that plots are sent to from R. See the same plot below when I instead export it to PDF.
