Hi,
I notice in R-3.1.1, if a package specifies a VignetteBuilder (such as knitr)
in its DESCRIPTION file, but
does not also depend on the specified package (in either Depends, Imports, or
Suggests), that R CMD check will say:
* checking package dependencies ... ERROR
VignetteBuilder package not declared: ‘knitr’
I'm glad this situation is now caught by R CMD check, but I think the message
text should be changed, because the message is confusing. Indeed, the
VignetteBuilder package *was* declared, in the VignetteBuilder line. The
problem is that there's no dependency on it, so no automated way to install it
for building or checking.
Can the message instead say something like:
Package 'knitr' must be in Depends, Imports, or Suggests field of DESCRIPTION
file.
?
A possible patch against trunk:
$ svn diff
Index: src/library/tools/R/QC.R
