How to set a theme when knitting RMarkdown to HTML?

阅读更多关于 How to set a theme when knitting RMarkdown to HTML?

问题 I have not been able to figure out how to set a knitr theme when converting RMarkdown to HTML. I have tried code such as > opts_knit$set(out.format = "html") > opts_chunk$set(highlight = TRUE) > knit_theme$set("olive") That does not affect the html output. I have tried this code before knitting the Rmd file as well as inside the first chunk. 回答1: Put a css file with the same name as your R file, but extension css, into the directory. Or see http://www.rstudio.com/ide/docs/authoring/markdown

问题 use "jsx" grammar in visual studio code. visual studio code report an error Please help me. Thanks!!! 回答1: The symbol "<" should appear in the same line with the tag name. For example, instead of doing that: return ( < button className="square"> {/*TODO*/} < /button> ) Do that: return( <button className="square"> {/*TODO*/} </button> ) If you want to split the tag to multiple lines, you can do it like that: return ( <button className="square" id="id" onClick={someFunc} > {/*TODO*/} </button>

https://zhuanlan.zhihu.com/p/104210726 武汉新型肺炎让这个春节变得痛心和揪心，也打乱了不少人的计划。我老家就在湖北，虽然本人并没有回老家，但是有不少亲朋好友在那边。此外，因为项目合作关系，我过去两年也差不多有一半的时间呆在武汉。但是，作为一个普通人，既非政府官员又非医护人员，或是可以直接提供贡献的相关工作人员，如果没有被感染，那么不管是不是在武汉，春节期间唯一能做的就是，老老实实做个宅男宅女，为2020年重新做一下规划，顺便给自己充充电。《银河系漫游指南》中的一句话曾经风行整个宇宙，那就是"Don't panic"，”不要恐慌“。另外，在我们这个星球上也有一个勇敢的人反复说过，我们无论面对任何困难，都不要害怕，微笑着面对它，奥利给！欢迎继续我们的学习。更改欢迎的文字内容虽然“Hello World”足够经典，但是似乎有点过于无趣。接下来我们可以尝试着更改一下要显示的文本内容。 1.在Canvas中，点击”Hello World”。当你选中这段文本时，会看到在Canvas视图和代码编辑器中相应的文本都会被高亮。在Canvas视图中：在代码编辑器中：之所以”Hello World”在两个地方同时被高亮，是因为它们代表着同一个事物的两种观察方式。代码编辑器中使用代码的形式显示了用户界面的内容
