Hello,

\Sexpr only displays one value.

Why don't you print your vector into a verbatim environment ?

<<echo=F,results=verbatim>>
print(rx)
@

But if you want to generate a table with xtable, one solution :

<<echo=F,results=tex>>
print(xtable(as.data.frame(t(rx))), include.rownames = F, include.colnames =
F)
@
