[R-pkg-devel] new maintainer sought for maps packages

I have made a beta version of the new maps package available at
If things go smoothly, I will probably submit it to CRAN early September.
I will also announce and clarify this on R-sig-Geo.
- Martin, the old data base is now called 'legacy_world', but can alternatively also be accessed as 'world' by calling world.legacy(TRUE) or by an environment setting. The last is meant for people who need to run code quickly without editing it.
- Jon, I quite liked the suggestion of enabling ISO3166. I have added a simple table and lookup function which could be used as
There will soon be an updated high resolution map too (it is already accessible in a test package https://github.com/adeckmyn/mapdataNE).

Please do make the new code available for testing. Those of us developing packages that import 'maps' would love the chance to test our code against the new version of the package.

The old data set will certainly stay for a while (or indeed indefinitely, why not). To make the transition as smooth as possible (I am aware that "maps" is used in more places than I can ever check myself) I am including the possibility of switching back to "legacy" mode using an environment variable (or an extra function "world.legacy(TRUE)"), so that any code that runs into trouble can be switched to the old database without needing to edit the code itself.
Would it be a good idea to make the new maps package (beta) available (e.g. via github) prior to submitting to CRAN? It is more or less ready. Given the many packages that call maps, this could give maintainers a chance to check things. For the moment, it's only the country borders & names that have changed.

I agree ... but the following is not about 'maps' in particular,
but package maintenance / compatibility ....
> As Ray mentioned, I (with his help & feedback) have been preparing an updated world map. I am going to be very cautious, but the many changes in country names (post-1990 Europe!) mean that any package or code that uses maps by calling map('world',region=...) to create a map using country names, could be affected. Maintainers of packages calling "maps" may want to contact me to make sure I don't break anything. In any case, I am currently testing a beta version that includes the old data set as a fall back.
I know these data sets are not very small, but I would still
strongly recommend that you
keep the old map, say as "world198x" (and change the "x" to a
digit if you know which one, or the "8x" to "7y" ... etc).
Storage and bandwidth have become considerably cheaper and so
the package could provide (almost) back compatibility ... and
also something interesting in itself (comparison of two very
similar maps with R; teaching, history, ...).
