内联代码和内联 LaTeX、R Markdown Pandoc 错误 43 [英] Inline code and inline LaTeX, R Markdown Pandoc error 43

问题描述

我现在已经遇到过几次这个问题，但是每当我尝试在我的 Rmd 文件中同时包含内联 LaTeX 和内联 R 代码时，我都会收到 Pandoc 错误 43.除了手动之外，一直无法找到解决方法添加 R 代码本来应该是什么.

I've run into this issue a couple times now, but whenever I try to include both inline LaTeX and inline R code in my Rmd file, I get Pandoc error 43. Never been able to find a workaround other than just manually adding in what the R code would have been.

```{r}
x_bar <- 4
```

The blue line above is the true $\lambda = 4$, and the red line is our 
$\hat{\lambda}_{MLE} = \bar{x} = $ `r x_bar`.

错误:

l.192 \$ \hat{\lambda}

推荐答案

在 $ 符号内移动内联 R 表达式:

Move the inline R expression inside the $ symbols:

```{r}
x_bar <- 4
```

$\hat{\lambda}_{MLE} = \bar{x} = `r x_bar`$.

Rmd 输出:

或者，将内联 R 代码留在外面，但删除第二个 $ 之前的尾随空格.

Alternatively, leave the inline R code outside but delete the trailing space before the second $.
