在 R Markdown 文档中格式化 R 输出

Question

I have a code that generates a text output. For example:

pick <- sample(c("Alex", "Greta", "Zoe"), 1)

Is there a way of formatting the result in an R Markdown documents.

Say something like this if I wanted it to appear in bold on the report.

**pick**

Answer 1

You can execute any R command in-text in an rmarkdown document without embedding it inside a chunk by placing it within ticks prefaced by the letter r (see below). You can then surround this r code with latex code, in this \\bf{foo} for bold font, bookmarked by $ . Try placing

inside an rmarkdown document. Or you could place the function in a chunk and then call it outside the chunk, anywhere in subsequent text, like this

The OP's chosen name is $\bf{`r pick`}$
