R help - Sep 2008 - Stacked Area Plot

Hi:

I've searched the archives and the Internet for hours but have yet to find a
way to do stacked area plots (like the kind in Excel) in R.  I think that
polygon may work but it would require a bit of manipulation of my data. I was
hoping for an easier way.

An example of what I'm trying to do can be found here:
http://jcharts.sourceforge.net/samples/stackedArea.html

Thanks,
Josip

These are pretty easy in ggplot2:

df <- data.frame(
  trt = rep(letters[1:3], each = 10),
  year =  rep(1:10, 3),
  value = abs(rnorm(30))
)

install.packages("ggplot2")
library(ggplot2)
qplot(year, value, data=df, geom="area", fill = trt)

The example pointed to below is a good example of fortune(197).

It is possible to do using polygon (and is probably not as hard as you are
making it), but there is probably a better way to present your data.  What
question are you trying to answer with this plot?

Hi Josip,
Look at stackpoly in the plotrix package.
