fSeries Technical Analysis rsiTA problem

Hello,

I’m trying to use the rsiTA() function but keep getting this error:

>rsiTA(tsx,14)
Error in "[.timeSeries"(close, 1:(length(close) - 1)) :
        only 0's may be mixed with negative subscripts

Here’s is the first three lines of my data:
>tsx[1:3,]
                                  close
2004-04-18 20:00:00 8702.82
2004-04-19 20:00:00 8602.98
2004-04-20 20:00:00 8573.05

I have 250 days of data.

Here’s the class
>class(tsx)
[1] "timeSeries"
attr(,"package")
[1] "fBasics"

And here’s my version:

>version
         _
platform i386-pc-mingw32
arch     i386
os       mingw32
system   i386, mingw32
status
major    2
minor    1.0
year     2005
month    04

I did load the libraries
library(fSeries)
library(fBasics)

Regards,
