Should you be using rsiTA(tsx[,2],14). If you look at the function you will 
see it is expecting just the values you want in the calculation.

If you give it a matrix it treats the whole matrix as being price data.

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

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

Regards,
