quantmod: addTA is broken?

You're absolutely right. I gave you a wrong example.

Let's say I have OHLC data from Cotton over the last 80 days. In a  
spreadsheet I got from a client the computed EMA values for cotton's  
daily high. So I import the computed values (the last 80) in R like  
this:

require(quantmod)
CottonSpreadsheet <- read.table(...)
CottonSpreadsheet <- last(CottonSpredsheet, 80)
OHLC <- last(Cotton, 80)
chartSeries(OHLC, type = "bars")
addTA(CottonSpeadsheet)

Now I got this error message:

Fehler in tav * 0.975 : nicht-numerisches Argument f?r bin?ren Operator
Zus?tzlich: Warning message:
In merge.zoo(lchob at xdata, ta, join = "left", retside = c(FALSE,  :
   Index vectors are of different classes: POSIXt POSIXt integer integer

I get the chartSeries(), but without the added addTA. I don't know why  
this first line of the error message is in German. I hope you can help  
me anyway.

Thank you, Michael

That's a warning message, not an error message.  This suppresses it:

suppressWarnings(plot(addTA(min55, on = 1)))

Hi there

I have here some financial charts which I did a couple of months  
ago with
quantmod. Today, I recharted my data with chartSeries(), which  
works fine.
As soon as I add some indicators with addTA() I get a error message.

For example:
require(quantmod)
require(TTR)
getSymbols("YHOO")
chartSeries(YHOO)
min55 <- runMin(YHOO$YHOO.Low, 55)
addTA(min55, on = 1)


I get this message:

Warning messages:
1: In merge.zoo(lchob at xdata, ta, join = "left", retside = c(FALSE,  :
Index vectors are of different classes: POSIXt POSIXt integer integer


How can I solve this?

Thank you, Michael
