Hello Megha and Jim, Thanks for your comments. The green bands actually correspond to data that looks like: 13 0 42 0 183 0 186 0 187 0 192 0 194 0 and so on. I plotted them using: plot(v[,1],3+v[,2],type="h",col="gray",lwd=5) and the rest of the data using points. The result is here: http://www.twitpic.com/md2li Thanks!
