Is it possible to change the ylim and xlim when the plot has already been drawn?

As an example, if I want to draw a plot with points 1-5 and add points 5-9, the following would work:

plot(c(1,2,3,4,5), ylim=c(0,10))
points(c(5,6,7,8,9))

However, if I don't know beforehand what numbers the to-be-added points will be (they could be 5-9, could also be 20-29), I can't set the ylim and xlim beforehand. I would like to be able to do something like the following (which does not work):

plot(c(1,2,3,4,5))
points(c(5,6,7,8,9), ylim=c(0,10))

Is something like this possible?

Solution

  • (Just for completeness.)

    This is almost certainly impossible in R base graphics. Other answers point out that it's doable in ggplot. It might be possible in something like the playwith package, although a short bit of playing around hasn't shown me a way to do it.
