Latex Sweave R - 页面自行旋转

Question

我刚开始使用 Sweave 和 Latex，并且遇到了一些小问题。 这是放入其自己的 tex 文件中的文档片段。

\documentclass[a4paper,10pt]{article}
\usepackage[dvips]{graphicx}
\usepackage{Sweave}


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%                                 END PREAMBLE                                %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


\begin{document}
\pagestyle{plain}

    \begin{figure}
    \begin{center}
<<fig=TRUE,echo=FALSE>>=
data=read.table("adult_dataset/adult.data", sep=",");

age=c(t(data[1]));
fnlwgt=c(t(data[3]));
education_num=c(t(data[5]));
cap_gain=c(t(data[11]));
cap_loss=c(t(data[12]));
hrs_week=c(t(data[13]));

labels=c("Age", "Final weight", "Education num", "Capital gain", "Capital loss", "Hours per week");

dframe=data.frame(age, fnlwgt, education_num, cap_gain, cap_loss, hrs_week);

par(mfrow=c(2,3)); 

for (i in c(1:6) ){
boxplot(dframe[i], main=labels[i]);
}
@
      \label{fig:boxplots}
      \caption{Boxplots of numerical features}
    \end{center}
    \end{figure}

\end{document}

Adult.data 是 http://archive.ics.uci .edu/ml/machine-learning-databases/adult/adult.data 我编译：

R CMD Sweave test.rnw && latex test.tex && dvipdf test.dvi

这产生了一个水平的页面。 它的尺寸是正确的，但旋转了 90 度。 不是图片，而是整个页面。

我可以做什么来解决这个问题？ 这是正常行为吗？

谢谢您的任何建议:)
