R help - Apr 2010 - Error: could not find function "tsts" tradesys package

Hi, I am pretty new to R and would like to follow the code in the paper
below, tradesys package. but I am stuck at the 2nd page where x<-tsts(spx)
is written. Could anyopne help me why I am getting an Error :"could not
find
function "tsts" ". I guess I need function call "tsts".
where can I find
that function ? I installed tradesys, zoo, RUnit packages but I don't know
why it gives me error. Thanks

Did you load tradesys after you installed it?
library(tradesys)

That seems to be a common beginner problem.

Thank you so much for your reply. On the first page of the paper, there are
logics which I typed

> library(TTR)
> data(spx)
> tail(spx)
,and it runs smoothly.
But it gives me an error at 
x <- tsts(spx)

Thanks, db

I think that this package is very much in the early stages
of development. It may be that the tsts function is still
just a gleam in the eyes of the developers. The paper that
you cite may be ahead of code development.

You need to take this up with the package authors.  After I install 
tradesys, and type vignette("tradesys"), I get a PDF that no longer 
contains the example in the PDF you reference from the web.  That 
particular version of the PDF that you reference is probably no longer 
relevant to the package.  Those functions are no longer distributed with 
tradesys, it appears.
