Subject: component chart
Hi
> How do I create a component chart using R? For example, given the
following data:
>
> 1994
> sales 80,000
> maintenace 20,000
>
> I want to create a horizontal bar graph where sales starts from 0 to
80,000 and maintenance starts from 80,000 to 100,000. I also want to display
the total as another bar starting from 0 to 100,000.

Sounds like you need the barplot() function.. For example (not very polished
:) ...
barplot(matrix(c(8,2,0,10),ncol=2), horiz=T)
... or (_slightly_ more polished) ...
barplot(matrix(c(8,2,0,0,0,10),ncol=2), col=c("red","green","blue"),
horiz=T, names=c("Components", "Total"),
legend.text=c("Sales", "Maintenance", "Total"),
space=0.5, xlim=c(0, 15))
Hope that helps
Paul
