Executive summary: getRemotePkgDepends seems to use the wrong default
string to (try to) download the CRAN package information.
=======================
Someone asked me about the behavior of tools::pkgDepends() , and in
investigating I discovered the following:
## tools:::getRemotePkgDepends
## undebug(tools:::getRemotePkgDepends)
tools::pkgDepends("GDD")
## Error in tools::pkgDepends("GDD") : package 'GDD' was not
found
## (correct!)
tools::pkgDepends("GDD",local=FALSE)
## Warning: unable to access index for
## repository http://mira.sunsite.utk.edu/CRAN
## ** should be OK, my settings work for update packages
## descending into the problem:
tools:::getRemotePkgDepends("GDD") ## same warning
tools:::getRemotePkgDepends("GDD",contriburl=NULL) ## OK!
tools:::getRemotePkgDepends("GDD",
contriburl=utils::contrib.url(getOption("repos")))
## OK
I think the problem is that getRemotePkgDepends has
default contriburl = getOption("repos")
which returns the 'head' of the repository:
> getOption("repos")
CRAN
"http://mira.sunsite.utk.edu/CRAN"
rather than
contrib.url(getOption("repos"))
[1] "http://mira.sunsite.utk.edu/CRAN/src/contrib"
Is this (as it seems to me) a bug? Should I report it as such?
