Hi,
Both following code examples plot bollinger band over the ticker main plotand
Williams Power 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)
See:
http://around-r.blogspot.it/2015/04/financial-data-exploratory-analysis_27.html
for examples.
In general, if you like to plot indipendently a trading indicator computed by
quantmod, you can do:
wpr <- addWPR(n=300)plot(wpr@TA.values, type='l') -- or any other R plot
library you like
as in @TA.values are stored trading indicator values for any indicator.
