knitr、tikzDevice 和 pgfplotstable 之间的冲突

Question

我使用knitr来编写由两个 组成的文档.Rnw。请考虑以下示例这个答案

main.Rnw

% !Rnw weave = knitr
% !TeX program = pdfLaTeX

\documentclass[final,12pt]{article}

\usepackage[a4paper]{geometry}
% \usepackage{pgfplotstable}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

<<include=FALSE>>=
  opts_chunk$set(concordance=TRUE, fig.width='8', fig.height='4', fig.pos='htb', out.width='\\textwidth')
@

\begin{document}
<<child-demo, child='include.Rnw', eval=TRUE>>=
@
\end{document}

和include.Rnw

% !TeX root = main.Rnw
% !Rnw weave = knitr
% !TeX program = pdfLaTeX

Let's plot the spectrum of $Na$:

<<'na', dev='tikz', fig.cap='Spectrum of $Na$', echo=FALSE>>=
  plot(c(1:10))
@

我注意到，取消注释该行，则\usepackage{pgfplotstable}生成的 pdftikzDevice大小为 0。

R这是在加载时编织控制台的详细输出pgfplotstable，如您所见，没有错误消息，但.pdf文件（但不是.tikz）的大小为 0。

可以pgfplotstable和 一起使用吗tikzDevice？
