[R] ggplot: connect points with line (not in order)

[Brian Smith]

Hi,

I am trying to connect points, but not in a different order than the
default value in ggplot. For example:

 xx <- sample(1:100,5)
  yy <- sample(1:100,5)

  mydat <- data.frame(xx,yy)
  print(mydat)

  ggplot(mydat,aes(xx,yy)) + geom_point() + geom_line()


I want to connect the points as they appear in mydat, and not necessarily
from the smallest value on the 'x' axis to the largest.

How can I do this?

thanks!
