Question

所以我已经使用R Markdown已有一段时间了，但是现在当我尝试编织文档时，它失败了。出现以下错误消息：

LaTeX错误：孤独的\ item-也许缺少列表环境。

我不确定为什么会发生这种情况，因为它以前对我有用。我的文档序言中有两个快捷方式：

\newcommand{\benum}{\begin{enumerate}}
\newcommand{\eenum}{\end{enumerate}}

我觉得这可能是造成我问题的原因，但是令人沮丧的是，在此之前我已经使用了很长时间，没有遇到任何麻烦。

任何帮助将不胜感激！

编辑：

这是我制作的最小文件。此小文档将不会编织，并且出现与上述相同的错误消息。

1. Here is a sample of some code I found online. The code chunk by 
itself will run fine, so that is not the issue.


```{r, echp=FALSE}
require(stats); require(graphics)
plot(cars, xlab = "Speed (mph)", ylab = "Stopping distance (ft)",
 las = 1)
lines(lowess(cars$speed, cars$dist, f = 2/3, iter = 3), col = "red")
title(main = "cars data")
plot(cars, xlab = "Speed (mph)", ylab = "Stopping distance (ft)",
     las = 1, log = "xy")
title(main = "cars data (logarithmic scales)")
lines(lowess(cars$speed, cars$dist, f = 2/3, iter = 3), col = "red")
summary(fm1 <- lm(log(dist) ~ log(speed), data = cars))
opar <- par(mfrow = c(2, 2), oma = c(0, 0, 1.1, 0),
            mar = c(4.1, 4.1, 2.1, 1.1))
plot(fm1)
par(opar)
```

编辑： 我一直在玩这个，这似乎是问题的一部分：

\begin{enumerate}

\item Using the default enumerate/itemize commands

\item DO work!

\end{enumerate}

但是...

\benum

\item Using the shortcut commands I made

\item DO NOT work!

\eenum

当我尝试单独运行代码块时，它们可以正常编译并生成所需的图形，因此我怀疑这是LaTeX的问题。但是我不是特克斯人，所以我不确定。

最初创建这些快捷键命令的原因是，我可以在这种类型的环境中使用大块R代码（请参见https://tex.stackexchange.com/questions/210003/how-can-i-nest-a-code-chunk-within-an-enumerate-environment-when-using-r-markdow）。

如以下某人所述，这可能与Pandoc有关吗？

谢谢！

不需要原始LaTeX。以下内容可以很好地产生您认为要达到的结果：

2. Thanks for the help. This document will not knit!

您也可以使用完整的命令：\begin{enumerate}和\end{enumerate}。我不确定为什么pandoc会将您的缩写从TeX文件中删除。

r markdown不编译
