Hi, I'd suggest you use ?rect for this.
Here's an example (I did not check whether it's correct...)
I also improved (but not checked :) your definition of cols.
Jonne.
X - seq(1:6)
Q - matrix(sample(X, 60, replace = T), nrow=6, byrow = T)
H - matrix(rep(1,60), nrow=6, byrow=T)
color - c(blue, orange, gold, indianred, skyblue4,
lightblue)
cols - matrix(data=color[Q], ncol=10)
# Old:
barplot(H, col=cols, width = c(0.1), xlim = c(0,3), beside=F)
# New:
x11()
plot(0, 0, type=n, ylim=c(0,nrow(Q)), xlim=c(0,ncol(Q)),
xlab=xlabel, ylab=)
xleft - rep(1:ncol(Q), each=nrow(Q))
ybottom - rep(1:nrow(Q), times=ncol(Q))
rect(xleft-1, ybottom-1, xleft, ybottom, col=cols)

Hi,
I'd like to construct a somewhat unusual barplot. In barplot I use
beside=F as I'd like to have stacked bars. The height of each bar is
always the same. Information in my plot is coded in the color of the
bar. I therefore need to be able so assign a different combination
(or order) of colors to each individual stacked bar.
In the example below, the combination of colors for my plot is
generated by X, Q, color and cols. These colors are supposed to fill
the stacked bars with the height of H. However, only the first column
of cols is used for all columns of H as barplot only allows me to
assign one vector for the color scheme of the entire barplot.
Does anybody know a way how I can assign each bar a potentially
unique color combination?
Thanks for your help!
Kim
