reChart() and addVo() bugs

[JulianFerry]

Description

The reChart() parameters show.grid and TA don't seem to do anything.

And addVo(log.scale = TRUE) displays an empty bar chart.

Expected behavior

I expected reChart() to remove/add a grid and TA to change the metrics displayed on the chart (such as Volume, EMA etc)

Minimal, reproducible example

getSymbols('GOOG')

candleChart(GOOG[1:100], TA = NULL)
addVo(log.scale = TRUE)
reChart(show.grid = FALSE, TA = c(addMACD()))

and

addVo(log.scale = TRUE)
