How to knit/Sweave to a different file name?

问题

By default, the knit/Sweave command will generate a tex file with the same name as the .Rnw file. I want to give it and the subsequent pdf file a different name is it possible?

回答1:

In the header of an .Rmd file, you can specify a file name:

---
title: "My title"
output:
  pdf_document:
    pandoc_args: [ 
      "--output=Custom_name.pdf" 
    ]
---

For .Rnw files you can directly call the function knitr::knit2pdf:

knit2pdf(input.Rnw, output="Custom_name.pdf") 

回答2:

@mrub,

knit2pdf(input.Rnw, output="Custom_name.pdf")

does this works for you ?? cause if I just use

knit2pdf("222.Rnw")

it'll gives me beautiful pdf file named "222.pdf", but if I use

knit2pdf("222.Rnw",output="lalala.pdf")

it will gives a pdf file named "lalala.pdf", with no error but the content is nothing but mess.

you know why would this happen?
