[R] how to connect dots by passing NA

This maybe a silly question. I'm trying to figure out a way to draw a line from a data set which contain NA. Say, I have a set of data as:

x <- c(1.1 2.2 NA 4.4 5.5)  ; y <- c(1:5) # as x,y of point a, b, c, d, and e.

I would like to plot this to a line by using dot-line to connect the two
adjacent points before and after the NA, something like: (a)______(b)......(d)______(e)

Any help will be very appreciated.
