Hi Dimitri,
I'm not proficient with base graphics, but here is a ggplot solution:
my.data.m - melt(my.data, id=date)
my.data.m$pn - +
my.data.m[my.data.m$variable %in% c(y, z), pn] - -
my.data.m$variable - factor(my.data.m$variable, levels=c(a, x, y, z))
my.data.m$Date -
Thanks a lot, Ista!

Dear R-ers!
Asking for your help with building the stacked area chart for the
following simple data (several variables - with date on the X axis):
### Creating a data set
my.data-data.frame(date=c(20080301,20080402,20080503,20090301,20090402,20090503,20100301,20100402,20100503),
I found a solution to my original question (see code below).
But I have a question about cosmetics, which I always find very challenging.
1. How can I make all dates appear on the X axis (rotated at 90
degrees vs. horizontal)?
2. How can I create vertical grid lines so that at each date there is
