I found the mac console and tried the first solution as well. It works fine.
R -e "Sweave('test.Rnw')" --args PatientId=2
<<echo=F>>=
argString<-commandArgs(TRUE)
print(argString)
argList<-strsplit(argString,"=")[[1]]
print(argList)
assign(argList[1],as.numeric(argList[2]))
print(PatientId)
@
results in:
\begin{Schunk}
\begin{Soutput}
[1] "PatientId=2"
\end{Soutput}
\begin{Soutput}
[1] "PatientId" "2"
\end{Soutput}
\begin{Soutput}
[1] 2
\end{Soutput}
\end{Schunk}
