Dear package maintainers, currently, 39 CRAN packages (not counting those on my exclude-from-Windows lists) are not passing the checks under Windows for R-2.5.0 alpha. Additional 157 (!!!) packages are only passing with one or more WARNINGS. Maintainers of failing packages will receive an automatical generated message today. In case your package does not pass the checks: Please remember that R-2.5.0 will be released in roughly two weeks and we are closely approaching beta status ... I'd like to ask all package maintainers to look into the check summaries at http://cran.r-project.org/src/contrib/checkSummary.html Thank you -- and keep the updates rolling in, Uwe Ligges
