[R-SIG-Finance] quantmod: how to add custom timeseries (addTA?)

[Josh Ulrich]

Michael,

I'll have to leave that question to Jeff Ryan, the package author.

You can avoid printing a legend for the lowest low by using the TA=
arg in chartSeries:
chartSeries(YHOO, TA="addTA(min55,on=1)")

Best,
Josh
