Don't use underscore in pkg name

Another thing I spotted is the example provided in https://github.com/ropensci/onboarding/blob/master/packaging_guide.md#-documentation
while it is just an example, better to avoid restricted characters there.

The mandatory ‘Package’ field gives the name of the package. This should contain only (ASCII) letters, numbers and dot, have at least two characters and start with a letter and not end in a dot. If it needs explaining, this should be done in the ‘Description’ field (and not the ‘Title’ field).

from: https://cran.r-project.org/doc/manuals/r-devel/R-exts.html#The-DESCRIPTION-file

So ?package_name and ?package_name-package would become ?package.name and ?package.name-package.

Good point about the underscore. We’ll fix that. However, at least I prefer no dots in package names - but of course they are allowed.

I understand, unfortunately dot is only reasonable character that can substitute space in pkg names. Otherwise user would need to use camelCase or ignore skip spacing at all.

Okay, it’s updated https://github.com/ropensci/onboarding/blob/master/packaging_guide.md#-documentation
