Let's suppose the values for the x axis are stored in 'values'.
barplot(values, col=c(rep("Red",3),rep(1,length(values)-8),rep("Blue",5)))

When you use the graphics functions from the lattice package (e.g.
xyplot) you can save them to a file (see ?save) because it creates an

Jon,
There are packages that fit mixtures of multivariate normals (mclust) and in
