Compile .Rnw file with command

Question

I have .Rnw file which generates me a report. In RStudio you compile it with button 'Compile PDF'.

But is there a way to compile this file with command in script and pass one character variable?

I tried to use function knit() but it only produces .tex file and I would like to obtain also pdf.

Thanks for your help in advance!

Answer 1

The function knit2pdf in the knitr package does the trick ;)
