Hi,

Both following code examples plot Bollinger bands over the ticker main plot
and William's Percent below the main plot.

1. chartSeries(YHOO,theme="white",TA = c(addBBands(200,2),
addWPR(n=300)))

2. chartSeries(IB,theme="white",TA = c(addBBands(200,2)))
   addWPR(n=300)

In general, if you like to plot indipendently a trading indicator computed by
quantmod,
you can do:

wpr <- addWPR(n=300)
plot(wpr at TA.values, type='l')   -- or any other R plot library you
like

as in @TA.values are stored trading indicator values for any quantmod indicator.
