如何控制rmarkdown/knitr文件的输出顺序（或如何防止浮动）

我遇到的问题与“”中提出的问题类似。在我的代码中，我有一个文本标题，后跟一个块，它使用四个knitr:：kable函数调用来显示四个表。奇怪的是，表1和表2显示在标题上方，表3和表4显示在PDF格式的输出中。这似乎与knitr允许对象浮动有关。我可以最好在knitr:：kable函数或chunk选项中关闭它吗？这是我的密码：

当我将

Comptable1有点迟了，但我刚刚在做这个。加载

选项中包含一些限制，似乎可以达到目的。特别是
latex\u options=c（“保持位置”）

comptable1i通常在我的标题中包含
\usepackage{placeins}
，然后将
\FloatBarrier
放在节标题之前，以防止浮动环境越过我想要的节之外。我添加了
标题包括：-\usepackage{placeins}
并修改了区块的标题，使其看起来像@Benjamin的注释所示的
{r，echo=FALSE，warning=FALSE，results='asis'，out.extra='FloatBarrier'}
。我仍然有同样的问题。我应该怎么做？如果你提供一个可复制的例子，就更容易提出具体的建议。@Benjamin当你的[sic]正确时，你是对的。我道歉。我用可复制的代码重做了。如果有帮助的话，我的knitr是v1.15.1，rmarkdown是1.3，RStudio是1.0.136，R是3.3.2谢谢你的帮助。我对你的答复速度感到敬畏。你的建议确实产生了一些不同的结果。我曾希望在2x2的网格中有4个表格和4个图表。现在我得到一个1x2行的图表，4个表格，然后是接下来的2个图表。添加另一个\FloatBarrier似乎有效。
