[R-SIG-Finance] Can't addMACD(). Is it a bug?

[Sávio M. Ramos]

Hi,

addMACD don't work. I am doing something wrong or it is a bug.

The code:

require(quantmod)
lista <- c("PETR4.csv", "VALE3.csv")   
for (i in lista){
x <- as.xts(read.zoo(i, sep=",", format="%Y-%m-%d", header=TRUE))
y <- to.weekly(x)
chartSeries(y, type="candlesticks", multi.col=TRUE, theme="white", subset='last 54 months', name=i) 
addMACD(fast = 12, slow = 26, signal = 9, type = "EMA", histogram = TRUE)
saveChart('pdf',width=25,height=13)


The two files is attached.
