Execution halted when I use knitr and Rscript with opts_chunk

Hello all,
I wrote a bash script in Mac OS that takes my .rnw file, knit it and then
makes a .pdf. To knit my file, I'm using the command
Rscript -e "library(knitr); knit('file.rnw', encoding='utf8')"
and everything works fine. However, I don't want the ## characters in my
final document. I tested, using R prompt, the following commands
library(knitr)
opts_chunk$set(comment=NA)
knit('file.rnw', encoding='utf8')
and they give me exactly what I want: the document without comments in the
R commands output. But if I try to run
Rscript -e "library(knitr); opts_chunk$set(comment=NA); knit('livro.rnw',
encoding='utf8')"
I get
Error: could not find function "opts_chunk"
Execution halted
as result. What am I doing wrong? How can I ask for options for my chunk in
knitr using the command line?
That looks like a bash problem: it appears to be replacing $set with a blank string. Use appropriate quoting or escaping to tell it not to do that. (I think using single quotes around the command will work; you'll need double quotes within it.) Duncan Murdoch
