I am using cacheSweave with a large LaTeX Sweave document. Rather than put
<<cache=true>>=
...snip...
@
in almost all of my code chunks, I would rather have cache=true
be the default, and use
<<cache=false>>=
...snip...
@
when I don't want a code chunk to be cached. How can I set this default argument for code chunks?
I am currently using the following code to compile the Sweave document:
library(cacheSweave)
Sweave(infile, driver = cacheSweaveDriver)
There are a number of ways to accomplish this, but using \\SweaveOpts{}
to set the option somewhere early in your *.Snw
file (eg in the document preamble) is probably the handiest:
\SweaveOpts{cache=TRUE}
As described in the Sweave manual, a \\SweaveOpts{}
statement anywhere in a documentation chunk will modify the defaults for " all code chunks after the statement ".
A couple of other options are mentioned here .
