Message-ID: <5728E988.9010207@oracle.com>

I need some help understanding a problem running the tests on the 
'digest' package. Initially, I got the message that the 'knitr' package 
was needed to run vignettes:

Running vignettes for package ?digest?
Error in loadVignetteBuilder(vigns$pkgdir) :
   vignette builder 'knitr' not found

So I installed the knitr package and all its dependents (?mime?, 
?stringi?, ?magrittr?, ?evaluate?, ?formatR?, ?highr?, ?markdown?, 
?stringr?, ?yaml?) . Now I get some different warnings:

Running vignettes for package ?digest?
   Running ?sha1.Rmd?
Warning messages:
1: In readLines(if (is.character(input2)) { :
   cannot open file 'sha1.Rmd': No such file or directory
2: In engine$weave(file, quiet = TRUE, encoding = enc) :
   The vignette engine knitr::rmarkdown is not available, because the 
rmarkdown package is not installed. Please install it.
3: In readLines(con) :
   cannot open file 'sha1.Rmd': No such file or directory

So why is sha1.Rmd missing? And why is it complaining about rmarkdown? 
Or more precisely why did it not install it as a dependent? It installed 
plain markdown.
