How can I implement Streamgraphs in R?
Streamgraphs are a variant of stacked graphs and an improvement on Havre et al.'s ThemeRiver in the way the baseline is chosen, layer ordering, and color choice.
Example:

Adding one line to Marc in the box's nifty code will get you much closer. (Getting the rest of the way will just be a matter of setting fill colors based on the max height of each curve.)
## reorder the columns so each curve first appears behind previous curves
## when it first becomes the tallest curve on the landscape
y <- y[, unique(apply(y, 1, which.max))]
## Use plot.stacked() from Marc's post
plot.stacked(x,y)
