我正在编织一个.Rmd文件,并希望有两个输出:每次运行编织时,html和一个purl'ed R脚本.这可以使用以下Rmd文件完成:
---
title: "Purl MWE"
output: html_document
---
```{r}
## This chunk automatically generates a text .R version of this script when running within knitr.
input = knitr::current_input() # filename of input document
output = paste(tools::file_path_sans_ext(input), 'R', sep = '.')
knitr::purl(input,output,documentation=1,quiet=T)
```
```{r}
x=1
x
```
如果你没有命名块,它工作正常,每次你运行knit()(或点击RStudio中的编织)时你得到html和.R输出.
但是,如果您将块命名为失败.例如:
title: "Purl MWE"
output: html_document
---
```{r}
## This chunk automatically generates a text .R version of this script when running within knitr.
input = knitr::current_input() # filename of input document …
