Brian, The easiest way is to create the entire timeseries and then set the missing values to NA. The NA values will lead to the gaps you want.

When I do a line plot I get the data and then a blank area where a line goes the tail of the last data point to the head of the next data point. Is there a way I can do a line plot where the gaps are not plotted?
