Question

我将使用该代码片段生成一个beamer演示幻灯片：

\section{PLK alle Mandanten und alle Fachbereiche}
\begin{frame}[fragile]
  \frametitle{PLK alle Mandanten und alle Fachbereiche}
  \begin{figure}
   <<echo=FALSE, warning=FALSE, out.width='\\textwidth', out.height='0.8\\textheight'>>=
    # Run source code to create scatter plot
    source("/bit_repositories/tm-plk/02_Analysis/GraficClientsDepartments.R")
    @ 
  \end{figure}
\end{frame}

在pdf prsentation中，我收到了这条错误消息：

gdata: Unable to load perl libaries needed by
read.xls()## gdata: to support 'XLX' (Excel 97-2004)
files.#### gdata: Unable to load perl libaries needed by
read.xls()## gdata: to support 'XLSX' (Excel 2007+)
files.#### gdata: Run the function

Excel XLS and XLSX formats.#### Attaching package:
'gdata'#### The following object is masked from

你有什么想法吗？非常感谢你。塞巴斯蒂安

Answer 1

运行功能

'installXLSXsupport()'

然后尝试再次安装gdata。

如果不起作用，请看： install gdata help page on cran

我为什么得到：gdata：无法加载perl库
