Hi folks,
I got the dreaded
Version contains leading zeroes
NOTE from a package check - the version was 0.0.1.000.
until I dug into the code and found the regex "(^|[.-])0[0-9]+" I didn't
realize the restriction was on leading zeroes *within a version
component* - I was interpreting it as leftmost in the whole version
(i.e., the initial 0).
I eventually found the documentation in ?package_version (feels like
it should also be pointed to somewhere in Writing R Extensions?
Numeric versions are sequences of one or more non-negative
integers, usually (e.g., in package ‘DESCRIPTION’ files)
represented as character strings with the elements of the sequence
concatenated and separated by single ‘.’ or ‘-’ characters. R
package versions consist of at least two such integers, an R
system version of exactly three (major, minor and patchlevel).
Doesn't say anything about leading zero(e)s here ...
"Zeroes" looks weird to me, but I see that "zeroes" is used on 26
lines in .Rd files in the R code base, while "zeros" is used on 36 lines
... so close to a tie. (Maybe someone wants to clean this up ... ?
Maybe a mini-project for the R bug sprint at the end of the summer?
Also, I'm sure this has been asked a few 100 times but: a new-to-CRAN
maintainer triggers a NOTE. Is there any way that a new user would know
that this was informational only? (There is also a
Note_to_CRAN_maintainers

wouldn't that be more appropriate here?)
cheers
Ben Bolker
