如何在 R-studio 中编织希腊符号以生成 pdf
How to knit a greek symbol in R-studio to generate a pdf
我正在使用 R studio markdown 和 knitr，它们都是很棒的东西。
我好像不能把希腊符号编织成pdf。

P-value
In statistics, the p-value is a function of the observed sample results (a statistic) that is used for testing a statistical hypothesis. Before performing the test a threshold value is chosen, called the significance level of the test, traditionally 5% or 1% [1] and denoted as α. If the p-value is equal or smaller than the significance level (\alpha)
现在我在linx mint 17 texlive 2013 Rstudio版本0.98.1062
结果：

Try running pandoc with --latex-engine=xelatex.
pandoc: Error producing PDF from TeX source

结果是 pandoc 抱怨 alpha 符号。所以生成的latex好像不能处理符号...
我想让 R studio 正确处理这个问题，而无需手动更改 tex 文件......理想情况下......
有什么建议吗？

对于 Rmarkdown 中的希腊符号，您可以使用内联公式，由 $ ... $ 表示，即两个 $ 符号。
试试这个：
If the p-value is equal or smaller than the significance level $\alpha$
