[R-pkg-devel] R-devel warning: You used a knitr feature that depends on the digest package.

[David Scott]

On a package I help maintain, we had a note from Kurt about a warning 
when building vignettes on R-devel.

It was

Warning: You used a knitr feature that depends on the digest package.

Checking the location of the error and googling it, I am pretty certain 
it comes from cache = true for a chunk in the vignette.

Adding digest as suggested package, I got no warning from winbuilder 
using R-devel, but submitting to https://builder.r-hub.io gave me a new 
warning from codetools at the same location as previously. Like digest, 
codetools is suggested by knitr.

Any advice? One thought is just take off cache = true.
