Question

我搞砸了一些东西，但我不知道在哪里看。我的猜测是，当我在emacs更新了一些软件包时发生了一些事情，但我不知道究竟是哪一个。任何帮助将不胜感激甚至运行如下的基本命令：

\begin{document}
<<test>>=
1+1
@ 
\end{document}

产生以下错误

label: test
Quitting from lines 39-40 (/tmp/tmp.rnw) 
Error in data.frame(..., check.names = FALSE) : 
  arguments imply differing number of rows: 3, 0
In addition: Warning messages:
1: In is.na(res[, 1]) :
  is.na() applied to non-(list or vector) of type 'NULL'
2: In is.na(res) : is.na() applied to non-(list or vector) of type 'NULL'

这是堆栈跟踪：

  arguments imply differing number of rows: 3, 0

Answer 1

今天遇到同样的问题。对我来说，这是通过将knitr packge从版本1.10.5升级到版本1.11，将评估包从版本0.7升级到版本0.7.2，将formatR软件包从版本0.9升级到版本1.2，以及从版本0.2升级的高版本软件包来解决的。 1到0.5版。

我按顺序对它们进行了升级，它只在升级后才起作用，所以我怀疑这是罪魁祸首。

叹息，看起来可能是时候更新.packages（）。

使用带有ESS的knitR时出错
