ファイル describe.Rnw を次のように作成すると:

\documentclass{article}

\begin{document}

<<results='asis'>>=
require(Hmisc)
latex(describe(cars), file="")
@


\end{document}

そしてそれをコンパイルしてみてください

library(knitr)
knit2pdf("describe.Rnw")

latex(describe()) の組み合わせで作成されたラテックスに文法上の誤りがあることを示すエラー メッセージが表示されます。

LaTeX errors:
P:/r/ellisp/test/describe.tex:65: LaTeX Error: Environment spacing undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help
Your command was ignored.
P:/r/ellisp/test/describe.tex:131: LaTeX Error: \begin{document} ended by \end{
spacing}.

See the LaTeX manual or LaTeX Companion for explanation.

生成されたラテックスが下に貼り付けられているのがわかります-行間が解析を混乱させている可能性がありますか? 私のセットアップ全体は新しく(実際にはテストモードです)、ドキュメントを正常にコンパイルしましたが、knitr は初めてですが、セットアップにも何か問題があるかどうかはわかりません。私の最初の質問は、何か間違ったことをしているのですか、それとももっと一般的な問題ですか??
