A package uses VignetteEngine: knitr; the package itself does not Suggests:
knitr, but it Suggests: BiocStyle which in turn Suggests: knitr. Nonetheless, R
CMD check fails indicating that a package required for checking is not declared.
Is it really the intention that the original package duplicate Suggests: knitr?
This is only with a recent R. In detail, with
$ Rdev --version|head -3
R Under development (unstable) (2014-06-14 r65947) -- "Unsuffered Consequences"
Copyright (C) 2014 The R Foundation for Statistical Computing
Platform: x86_64-unknown-linux-gnu (64-bit)
trying to check the Bioconductor genefilter package leads to
$ Rdev --vanilla CMD check genefilter_1.47.5.tar.gz
* using log directory ‘/home/mtmorgan/b/Rpacks/genefilter.Rcheck’
* using R Under development (unstable) (2014-06-13 r65941)

* checking for file ‘genefilter/DESCRIPTION’ ... OK
* this is package ‘genefilter’ version ‘1.47.5’
* checking package namespace information ... OK
* checking package dependencies ... ERROR
VignetteBuilder package not declared: ‘knitr’
See the information on DESCRIPTION files in the chapter ‘Creating R
packages’ of the ‘Writing R Extensions’ manual.
I interpret this to mean that knitr should be mentioned in Suggests: or other
dependency field. The package does not Suggests: knitr, but it does Suggests:
BiocStyle, which itself Suggests: knitr. The author knows that they are using
the BiocStyle package for their vignette, and the BiocStyle package suggests the
appropriate builder.
