Hi,
Wouldn't it be awesome if package.skeleton() could be used to
produce, well... a package skeleton? In a fresh R session:
Empty packages are almost identical, differing only in the name entry in
the DESCRIPTION file.
And also in the name and content of man/mypkg-package.Rd
So why not do this once manually, and just copy it
into place the next time you need one? Why do you ask other people to do
work that is trivial for you to do?
I'm reporting a bug. Bugs that have easy workarounds are still bugs
aren't they? In that particular case, the culprit is this line:
have <- unlist(lapply(list, exists, envir = environment))
which could be replaced by this one:
have <- vapply(list, exists, TRUE, envir = environment)
so at least the code doesn't break before the test for "no R objects
specified or available" can be performed. It still doesn't make sense
that package.skeleton() is not supporting that case though...
Thanks,
H.

Error in !have : invalid argument type
This (not very informative) error message seems to occur because
I'm trying to create a skeleton with no flesh on it:
> foo<- function() {}
> package.skeleton("mypkg")
Creating directories ...
Creating DESCRIPTION ...
Creating NAMESPACE ...
Creating Read-and-delete-me ...
Saving functions and data ...
Making help files ...
Done.
Further steps are described in './mypkg/Read-and-delete-me'.
A package with nothing defined in it is still a valid package.
Thanks,
H.
