This happens because 'plot' is based on plotting the entire series of points which you give it, whereas your data (on the basis of the 'time' variable) consists of 2 series. So the solution is to plit it: plot(C1[(1:8),],type="l",col="green") lines(C1[(9:16),],col="blue") (where I've added the "col" option to illustrate how to identify the two series by colour).
