quantmod (version 0.4.17)

setTA: Manage TA Argument Lists

Description

Used to manage the TA arguments used inside chartSeries calls.

Usage

setTA(type = c("chartSeries", "barChart", "candleChart"))
listTA(dev)

Arguments

type

the function to apply defaults TAs to

dev

the device to display TA arguments for

Value

Called for its side-effect of setting the default TA arguments to quantmod's charting functions.

Details

setTA and unsetTA provide a simple way to reuse the same TA arguments for multiple charts. By default all charting functions will be set to use the current chart's defaults.

It is important to note that the current device will be used to extract the list of TA arguments to apply. This is done with a call to listTA internally, and followed by calls to setDefaults of the appropriate functions.

An additional way to set default TA arguments for subsequent charts is via setDefaults. See the examples.

Examples

# NOT RUN {
listTA()
setTA()

# a longer way to accomplish the same
setDefaults(chartSeries,TA=listTA())
setDefaults(barCart,TA=listTA())
setDefaults(candleChart,TA=listTA())

setDefaults(chartSeries,TA=substitute(c(addVo(),addBBands())))
# }
