Quick guess: Your transformation from priceData to EMA(priceData) changed the x-axis data representation. Maybe you moved from times to observation count. Make sure it remains the same, and your good. For a simple solution directly in R, look up my bollinger bands examples on the R Graph Gallery page. For a high-end solution, look at the quantmod package and the quantmod site. Lastly, the question really belongs on the r-sig-finance list which you should subscribe to in order to post.
