Hello,
I want to have a sweave document that will include a variable number of tables in. I thought the example below would work, but it doesn't. I want to loop over the list foo and print each element as it's own table.

\documentclass[a4paper]{article}
\usepackage[OT1]{fontenc}
\usepackage{longtable}
\usepackage{geometry}
\usepackage{Sweave}
\geometry{left=1.25in, right=1.25in, top=1in, bottom=1in}
\listfiles
\begin{document}
<<label=start, echo=FALSE, include=FALSE>>=
startt<-proc.time()[3]
library(RODBC)
library(psych)
library(xtable)
library(plyr)
library(ggplot2)
options(width=80)
#Produce some example data, here I'm creating some dummy dataframes and putting them in a list
foo<-list()
foo[[1]]<-data.frame(GRP=c(rep("AA",10), rep("Aa",10), rep("aa",10)), X1=rnorm(30), X2=rnorm(30,5,2))
foo[[2]]<-data.frame(GRP=c(rep("BB",10), rep("bB",10), rep("BB",10)), X1=rnorm(30), X2=rnorm(30,5,2))
foo[[3]]<-data.frame(GRP=c(rep("CC",12), rep("cc",18)), X1=rnorm(30), X2=rnorm(30,5,2))
foo[[4]]<-data.frame(GRP=c(rep("DD",10), rep("Dd",10), rep("dd",10)), X1=rnorm(30), X2=rnorm(30,5,2))

\section{Text}
This document was created on \today, with \Sexpr{print(version$version.string)} running
on a \Sexpr{print(version$platform)} platform. It took approx \input{time} sec to process.
<<label=test, echo=FALSE, results=tex>>=
cat("Foo")
@
that was a test, so is this
<<label=table1test, echo=FALSE, results=tex>>=
print(xtable(foo[[1]]))
@
\newpage
\subsection{Tables}
<<label=Tables, echo=FALSE, results=tex>>=
for(i in seq(foo)){
cat("\n")
cat(paste("Table_",i,sep=""))
cat("\n")
print(xtable(foo[[i]]))
cat("\n")
}
#cat("<<label=endofTables>>= ")
@
<<label=bye, include=FALSE, echo=FALSE>>=
endt<-proc.time()[3]
elapsedtime<-as.numeric(endt-startt)
@
<<label=elapsed, include=FALSE, echo=FALSE>>=
fileConn<-file("time.tex", "wt")
writeLines(as.character(elapsedtime), fileConn)
close(fileConn)
@
\end{document}
Here, the table1test chunk works as expected, and produced a table based on the dataframe in foo[[1]], however the loop only produces Table(underscore)1....
Any ideas what I'm doing wrong ?
