To superimpose anything onto a barplot you just need to know the x axis locations of the bars, then everything behaves as expected. You can find this by writing the barplot to an object, ie:
bp <- barplot(c(1:5),beside=TRUE) bp is now a matrix containing the actual x axis locations of the bars (in this case 0.7, 1.9, 3.1, 4.3 and 5.5). You can now add things to this barplot, such as: lines(bp,1:5) which in this case adds a line joining the tops of all the bars. You should be able to adapt this simple example to your situation.
