data(tli)
 ## Demonstrate data.frame
 tli.table <- xtable(tli[1:10,])
 digits(tli.table)[c(2,6)] <- 0
 print(tli.table,floating=FALSE)

I used above R code to generate Latex code as below.  However, Tex Live can't run the code after I code and paste it to Tex Live.  The reasons are: at the very beginning of the Latex code, two lines are missing:
\documentclass[11pt]{article}
\begin{document}

At the end of the Latex code, one line is missing: \end{document}.  I have to type those three lines in TeX Live in order to run the code.  Does anyone know how to add those three lines in xtable function in R?  Thanks.
