This is my code for the table, I was expecting siunitx to add the comma to the numebers with more than 3 digits, i.e., 3456 -> 3,456 but it does not happen, the numebers without decimals are shown as they are. I tried some code found in answers in this site that works for people but not for me. Any help?

 \usepackage{siunitx}
 \sisetup{group-separator={,},group-minimum-digits={3},output-decimal-marker={.}}

  \begin{table}
   \centerfloat
   \caption{Descriptive statistics of Expedia and Tripadvisor datasets.}
   \label{tab:stats}
  \scalebox{1}{
  \begin{tabular}{l S S}
\hline
\multicolumn{1}{c}{Statistics}&\multicolumn{1}{c}{Tripadvisor} &\multicolumn{1}{c}             {Expedia} \\
\hline
Total Hotels & 5356 & 3701 \\
[1em]
Average Reviews per Hotel & 68.3 & 154.93 \\
[1em]
Average Review Length & 665.4 & 210.23 \\
[1em]
Average Review Rating & 3.9 & 4.0 \\
[1em]
Average Hotel Review Rating & 3.6 & 3.9 \\
[1em]
Total Responses & 102564 & 13123 \\
[1em]
Average Response per Hotel & 22.3 & 3.9 \\
[1em]
Average Response Length & 397.8 & 251.3 \\
\hline
\end{tabular}
}
\caption*{}
\end{table}

    Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Nathanael Farley Oct 9 '14 at 15:43
  • The siunitx-package will only format numbers in the \num{}-command. – René B. Christensen Oct 9 '14 at 16:11
  • this is not what I understood. For example here tex.stackexchange.com/questions/121387/… look at the first answer. That is what I want but the example does not work for me. – user63979 Oct 9 '14 at 16:39
  • This is 'works for me': can you add \listfiles to your input and report the version information this adds to your .log file? – Joseph Wright Oct 9 '14 at 21:12
  • @user63979: I stand corrected. I just tried compiling your document, and your current code seems to work on my machine (at least in the memoir document class). – René B. Christensen Oct 10 '14 at 14:15
