Sweave中是否有与\ Sexpr {}等效的R Markdown? [英] Is there an R Markdown equivalent to \Sexpr{} in Sweave?

问题描述

在knitr中使用R Markdown是否等效于Sweave中的\Sexpr{}?

Using R Markdown in knitr is there an equivalent to \Sexpr{} in Sweave?

推荐答案

是.您可以使用

`r your_expression_here`

类似

2+2 is: `r 2+2`

应产生:

2+2 is: 4

我最初发现很难弄清楚您可以在knitr中使用的每种不同样式(html，markdown，sweave等)的不同语法是什么，然后求助于Yihui的最小示例(效果很好)，但是如果您可以阅读正则表达式，则可以查看

I initially found it a little difficult trying to figure out what the different syntax was for each of the different styles you could use in knitr (html, markdown, sweave, ...) and resorted to looking at Yihui's minimal examples (which do a good job) but if you can read regular expressions you can view the default pattern definitions. You even have the option of defining your own syntax if you want.
