  1. Is it possible to change the ylim and xlim when the plot has already been drawn?
  2. > plot(c(1,2,3,4,5), ylim=c(0,10))
  3. > points(c(5,6,7,8,9))
  4.        
  5. > plot(c(1,2,3,4,5))
  6. > points(c(5,6,7,8,9), ylim=c(0,10))
  7.        
  8. df <-data.frame(age=c(10,10,20,20,25,25,25),veg=c(0,1,0,1,1,0,1),extra=c(10,10,20,20,25,25,90))
  9.  g=ggplot(data=df,aes(x=age,y=veg))
  10.  g=g+stat_summary(fun.y=mean,geom="point")
  11.  g
  12.        
  13. a<-g+coord_cartesian(xlim=c(0,100))
  14. a+geom_point(data=df,aes(x=extra,y=veg))
  15.        
  16. require(ggplot2)
  17. data(mpg)
  18.  
  19. g = ggplot(mpg, aes(cyl, cty)) + geom_point() + xlim(5, 8)
  20. g
  21. g + xlim(4,8)
  22.        
  23. my.data <- seq(0,5)
  24. my.points <- seq(5,9)
  25. plot(my.data, ylim=c(0,max(my.data,my.points)))
  26. points(my.points)

  31. points(my.points)
