只有前三个 wordcloud2 出现在 knit R markdown 中

如何解决只有前三个 wordcloud2 出现在 knit R markdown 中

我正在 R 中开展一个项目，该项目涉及生成大量 wordcloud（使用 wordcloud2），其中大部分都在自己的块中。在 R 降价本身中，一切正常并且看起来很好。但是，当我将 markdown 编织到 html 文件中时，只显示前三个 wordcloud。在做了一些测试之后，这似乎不是任何特定 wordcloud 的问题——如果我将 include=F 添加到前三个 wordcloud 块中的任何一个，从而将它从编织的 html 中删除，第四个 wordcloud 将显示出来，所以编织的html中仍然有3个。编织的 html 仍然会为它没有显示的任何 wordcloud 留出空白（在前三个之后），但没有任何东西会占据它。如果我增加该块的图形尺寸，空白大小会增加但仍然没有 wordcloud。我很想弄清楚这一点，以便 html 显示我告诉它的所有内容。

谢谢！

wordcloud2(trial)

wordcloud2(trial) #these three should each be in their own chunks
