Hi: I am trying to create a dynamic latex table using \Sexpr{} but it's not evaluating it. I also tried the example below without Sweave and also fails. I have also copied the Sweave.sty to my working directory but nothing seems to work. Do I need to have certain package in order to run \Sexpr{}?
\documentclass[a4paper]{article} \usepackage{C:/R/R-2.8.1/share/texmf/Sweave} \begin{document} <<echo=false,results=hide>>= library(lattice) library(xtable) data(cats, package="MASS") @ \section*{The Cats Data} Consider the \texttt{cats} regression example from Venables \& Ripley (1997). The data frame contains measurements of heart and body weight of \SExpr{nrow(cats)} cats (\Sexpr{sum(cats$Sex=="F")} female, \Sexpr{sum(cats$Sex=="M")} male). A linear regression model of heart weight by sex and gender can be fitted in R using the command <<>>= lm1 = lm(Hwt~Bwt*Sex, data=cats) lm1 @ Tests for significance of the coefficients are shown in Table~\ref{tab:coef}, a scatter plot including the regression lines is shown in Figure~\ref{fig:cats}. \SweaveOpts{echo=false} <<results=tex>>= xtable(lm1, caption="Linear regression model for cats data.", label="tab:coef") @ \begin{figure} \centering <<fig=TRUE,width=12,height=6>>= print(xyplot(Hwt~Bwt|Sex, data=cats, type=c("p", "r"))) @ \caption{The cats data from package MASS.} \label{fig:cats} \end{figure} \begin{center} \end{center} \end{document} Felipe D.
