Trying this, but am hung up on directing to STDOUT. I tried just using:
,---
| print(paste("[../plots/",filename,"]",sep=""))
`---
but just ended up with a bunch of strings in the pdf output. In
googling around I found this on SO:
- http://stackoverflow.com/questions/4112896/how-can-i-redirect-r-warning-messages-to-stdout
So I tried:
,---
| sink(stdout(),print(paste("[../plots/",filename,"]",sep="")))
`---
But nothing gets printed into pdf at all.
---
Actually, I revisited the above plaint print() statement to see what's
going on and the #+results block contains files like so:
,---
| [1] "[../plots/filename.pdf]"
`---
How do I strip the [1] and the quotes?
Thanks!
