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.

Thank you so much for your reply. On the first page of the paper, there are
logics which I typed
library(tradesys)
library(TTR)
data(spx)
tail(spx)
,and it runs smoothly.
But it gives me an error at
x <- tsts(spx)
Thanks, db
