Knitr没有在R代码块中包装行

Question

我的knitr报告中的R代码块有问题，它们几乎没有用R代码在我的所有块中包装行。

这是一个典型的Rmd文件，其中包含以下块：

```{r}
batch_merged <- sqldf(c("update batch_merged set winning = 'mix' where (Homophily_Count BETWEEN 1 AND Agents_Count - 1) or (Heterophily_Count BETWEEN 1 AND Agents_Count - 1) or (Preferential_Count BETWEEN 1 AND Agents_Count - 1)", "select * from batch_merged"))
batch_merged <- sqldf(c("update batch_merged set winning = 'hom' where Homophily_Count = Agents_Count", "select * from batch_merged"))
batch_merged <- sqldf(c("update batch_merged set winning = 'het' where Heterophily_Count = Agents_Count", "select * from batch_merged"))
batch_merged <- sqldf(c("update batch_merged set winning = 'pre' where Preferential_Count = Agents_Count", "select * from batch_merged"))
winning <- sqldf("select OptionGroup, sum(CASE WHEN winning='hom' THEN 1 ELSE 0 END) as homophily, sum(CASE WHEN winning='het' THEN 1 ELSE 0 END) as heterophily, sum(CASE WHEN winning='pre' THEN 1 ELSE 0 END) as preferential, sum(CASE WHEN winning='mix' THEN 1 ELSE 0 END) as mixed from batch_merged group by OptionGroup")
# print.data.frame(winning)
```

我用这条指令创建报告：

knit2html("raport-partC.Rmd","raport-parcC.html")

任何想法都赞赏。谢谢！

根据评论，我应该首先正确格式化我的R代码以坚持恒定的字符宽度，而不是编织后 - 如果仍有任何问题 - 手动编辑我的页面和CSS。我在可能的情况下结束这个问题。感谢。
