First of all, wonderful package - thank you for your work Yihui.
But could you tell me how to set global options in .Rmd document. Simple example:

x <- rnorm(10)  
x

I do not set comment in every chunk. How to change the default ## into >?

That setting sounds unusual... Anyway, use opts_chunk$set(comment = '>') if you really like the output has a prefix >. I suppose you probably want opts_chunk$set(prompt = TRUE), though.

Thanks for the great package Yihui.

I've worked through several examples, but can't seem to get the images to display in the tufte-book class, although they compile in their own document environment. The maxwidth var seems to go missing in my child documents with the chunks. I've also tried to define the parent but still no luck.

I see you have worked with the tufte-handout, do you have any suggestions for the book class?

Sorry, I guess I cannot help without a minimal reproducible example... in theory, child documents are included in parent documents, so maxwidth must be applied to them.

Dear Yihui Xie, I have been struggling trying to embed a ggvis object into a pdf using knitr. I'm facing difficulties installing vega, I read that it has problems with windows users. Do you know if there is an alternative method do this? Thanks a lot.
