Try this. gl(2,50) is such that the first 50 points are series 1 and the second 50 points are series 2. The scales= argument defines the positions of the tick marks and the xlim= argument defines the x axis limits. The layout puts the panels on top of each other rather than side by side. strip = FALSE eliminates the strip above each panel. type= says we want lines. The panel function puts points at the grid locations in each panel and then calls xyplot to plot the lines.
