当指标覆盖在另一个图表上时,如何让addTA()不打印图例?

标签: r quantmod

在此代码中:

library(quantmod)
getSymbols("YHOO")
candleChart(YHOO)
addTA(Cl(YHOO)/2, legend = "", on = NA )

addTa()的图例参数按预期工作。

但如果我让on = 1

,那么该参数的相同值就不起作用
library(quantmod)
getSymbols("YHOO")
candleChart(YHOO)
addTA(Cl(YHOO)/2, legend = "", on = 1 )

它显示Cl(YHOO)/2:后跟最后调整后的价格作为图例。如何删除此图例?此外,是否可以删除图表上显示的最后价格?我在chartSeries()文档中找不到任何提及的内容。

以下是我sessionInfo()的输出:
