问题描述
在我的投影仪演示文稿的序言中加入\usepackage{Sweave}时，投影仪将忽略字体更改，例如\usepackage{helvet}.
When I include \usepackage{Sweave} in the preamble of a beamer presentation, beamer ignores changes to font, e.g., \usepackage{helvet}.
这是一个最小的示例:
\documentclass[professionalfonts]{beamer}
\usepackage[T1]{fontenc}
\usepackage{helvet}
\usepackage{Sweave}
\begin{document}
\begin{frame}
Lorem ipsum dolor sit amet, consectetur adipisicing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna
aliqua. Ut enim ad minim veniam, quis nostrud exercitation
ullamco laboris nisi ut aliquip ex ea commodo consequat.
\end{frame}
\end{document}
文本设置为现代计算机，而不是helvetica.如果您注释掉\usepackage{Sweave}，则将文本设置为helvetica.
The text is set in computer modern, rather than helvetica. If you comment out \usepackage{Sweave}, then the text is set in helvetica.
因此，我的问题是:是否可以更改包含Sweave内容的投影仪演示文稿中的字体?
我意识到这里的示例不包含任何实际的"Sweable" R代码，但这似乎无关紧要，因为不必要的字体切换行为似乎是由Sweave.sty引起的.我更大的目标是将pgfSweave与Beamer一起使用，但是我在这里也遇到了同样的问题.我想我已将其追踪到\usepackage{Sweave}.
I realize that my example here does not include any actual, "Sweable" R code, but it seems to not matter, because the unwanted font-switching behavior appears to result from Sweave.sty. My bigger goal is to use pgfSweave with beamer, but I'm having the same problem there. I think I have tracked it down to \usepackage{Sweave}.
