[R] component chart

Hi

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
