Stacked barplot with two stacked bars besides each other
Thanks. That is definitely in the right direction, but firstly I would like yoda1:var1 next to yoda1:var2, not as currently yoda1:var1, yoda2:var1, yoda1:var2, yoda2:var2. Additionally, I would like the gap between samples to be greater than the gap between variables. Many thanks Dan

Try this:
barplot(cbind(as.matrix(var1), as.matrix(var2)), names.arg = LETTERS[1:4])

Hi,
I have a particular barplot I would like to generate, but I am having
trouble getting it to work. What I would like is in effect two barplots
with stacked bars merged into one. For example, I have two samples
(yoda1,yoda2) on which I measure whether two variables (var1,var2) are
present or absent for a number of measurements on that sample.
> var1 <- data.frame(yoda1=c(3,7), yoda2=c(1,9))
> var2 <- data.frame(yoda1=c(8,2), yoda2=c(5,5))
For each variable I can plot a barplot
> barplot(as.matrix(var1))
> barplot(as.matrix(var2))
I would like to join these together, so that for each sample there are
two stacked bars next to each other, one for var1 and the other for
var2. I was thinking something like:
> barplot(list(as.matrix(var1),as.matrix(var2)))
would work, but it didn't.
Any suggestions you could make would be great.
Dan
