sankey plot R 不显示 markdown

Question

I'm working on an R markdown document but am stuck with a "sankey chart" element. The Sankey element works fine in its code, but when I knit markdown the element doesn't show up in the markdown (or is just blank[?]).

When i'm running the code the diagram comes out just fine enter image description here , but when i'm knit'ing it, it doesn't show, and just leaves the markdown-page blank.

Any help is appreciated. Thanks!

I got it to work. It was headlines -tabset, that was the problem. I edited them and that fixed it
