[R-SIG-Finance] Quantmod problem: calling Charts from function

Hello,

I get different behaviour calling candleChart directly versus calling it in a function: only one of multiple technical analyses is plotted.

Example:
#####################################
library(quantmod)
getSymbols("AAPL",src="yahoo") 
# WORKS
candleChart(AAPL,multi.col=TRUE,theme="white")
addBBands()
addMACD()
addMACD()
# Doesn't work
test<- function(x) {
	candleChart(x,multi.col=TRUE,theme="white")
 	addBBands()
	addMACD()
	addMACD()
}
test(AAPL)
# only shows first MACD not 2nd unlike in direct call
###########################

Any pointers where the different behaviour comes from?
Many thanks
Daniel Probst
