[R] R graphics question: "binary" bar chart

[Stephan Spat]

Hello!

I would like to visualize the hospitalization within one year of several
patients using a bar chart. For each patient the stay in a hospital
should be illustrated with a dark colour a if there is a stay at home
between 2 hopital stays, it should be illustrated with a bright colour.

e.g.

P1       |//////|      |///|             |////////|
P2                 |//////////|
P3          |//|   |////|       |///|    |//|
    Day1------------Day100---------------------------------Day365


legend:
Px	 Patient with id x
|///|    Hospital stay (length of bar symbolizes length of stay)
          Place between 2 hospital stays symbolizes stay at home
	 (not in hospital)

Are there any package which can do that? If not, how can I implement
this in R?

Thanks a lot
