I also see this. It seems that the 100th point plotted is not connected to the 101st, regardless of the actual data values. A more visually dramatic example is

    x<-seq(0,8*pi,length=102)
    plot(x,cos(x),type="l")

which makes it clear that the problem isn't just something like antialiasing. The gap doesn't appear in pdf().
